AGENTS HAVING HIGH NITROGEN CONTENT AND HIGH CATIONIC CHARGE BASED
ON DICYANIMIDE, DICYANDIAMIDE OR GUANIDINE AND INORGANIC AMMONIUM
SALTS

BACKGROUND OF THE INVENTION

The present invention relates to compositions of matter which are useful in chemical, pulp and paper, mining, clay, textile and leather industries. The polymers and (co)polymers of the present invention can be used in pulp and paper industries as pitch control agents, as chemical additives and adjuvants such as felt cleaner, as tack reducing agents on paper machines, as paper sizings, as retention aids, additives for colorants, and as antistatic agents. The inventive materials are also useful as flame retardants in flame retardant formulations, as dispersing agents, as antimicrobials, as coagulants and as flocculating agents. Further still, the novel polymers and copolymers described herein are useful in compositions with sequestering agents.
The present invention further relates to linear and/or cyclic guanidine or polyguanidine or (co)polyguanidine, dicyanamide, polyguanidine ammonium chloride(PGAC) or polyguanidine urea ammonium chloride (PGUAC) which are further reactedwith cationic charged or multiply cationic charged reactive agents of the non-formaldehyde type.

21 4~055 Such products having cationic or multiple cationic charge are disclosed, for example, in U.S. Patent Nos. 4,891,422 and 4,902,779 (now Re 34,486), and in 5,135,613, these disclosures being fully incorporated herein by reference. U.S.
Patent Re 34,486 describes cationic polyguanidine and its alloy-type formation by 5 condensation according to the following reaction:

_ n (I) where n is less than 100,000. The (co)polyguanidines are defined by the formulaeB(1), B(3), B(4), B(5), B(6), B(7) as disclosed in Re 34,486, and are further reacted with cationic or multiply cationic charged agents defined by formula B(2) and agents (a, b, c, d, e, f, g, h, i) also disclosed therein. The R1 and R2 moieties are well defined in U.S. Patent Re 34,486 and its contents are fully incorporated herein by reference.
The guanidines or polyguanidines of structural formula (I) according to Re 34,486 differ from those of the present invention. The reaction of dicyandiamidewith alkyl amine proceeds via a condensation process to form an inert (i.e., uncharged or non-cationic) guanidine or polyguanidine with high insoluble matter and is well known. For example, these products are described in:
German Patent No. 851,001, Ger. Offen. DE 3,400,051, U.S. Patent Nos.
2,649,354; 3,873,266; 3,488,742; 4,410,652; 4,439,303; 4,439,208; and in Fr.
Demande FR 2 567 897.
French patent 2,567,897 and the references cited therein describe condensation products for fixing, dyeing, and printing, and which are prepared by catalytic condensation of alkyl amine with dicyandiamide in the presence of a zinc chloride catalyst (optionally containing less than 50 mol% dicarboxylic acid or its ester and also aminoplasts, epihalohydrins and/or formaldehyde or its donors).
However, the use of zinc in the condensation process poses environmental concerns 5 such as restrictions regarding the disposal of waste zinc which is a known water pollutant.
U.S. Patent No. 3,873,266 and 2,649,354 disclose that these condensation products from diethylenetriamine and dicyandiamide are not homogeneous, are very difficult to be handle, and are not completely water soluble. The '266 patent 10 describes the process of making a solution from condensation products of (A) polyamines and (B) cyanamides, or their water soluble salts. These processes, however, require long reaction time and are very unpractical on an industrial scale.
U.S. Patent No. 4,410,652, incorporated herein reference, describes the use of the reaction product from an amine with cyanamide, dicyandiamide, guanidine or 15 biguanidine as a wet fastness agent for direct dyes on cellulose substrates. The '652 patent describes an in situ condensation in situ process which is very difficult when carried out on an industrial scale. A drawback to this kind of process is that the reaction mixture cannot properly be mixed. Hence the reagents do not properly migrate within the reaction chamber, leading to non-uniformity of reaction product.
20 This type of process also suffers from an inability to control the rate of decomposition of -CN groups. Accordingly, the dicyandiamides, dicyanamides, diguanidines or biguanidines thus formed can undergo cracking through loss of -CN radicals.

SUMMARY OF THE INVENTION
The present invention relates to non-formaldehyde cationic or multiply cationic 5 charged guanidine or polyguanidine products. These compounds are prepared from an inorganic ammonium salt, such as ammonium halide, ammonium sulfate, ammonium nitrate, an amine and occasional urea and from a monomer selected from the following:
1. Dicyandimide and its salts (preferably, ammonium, calcium or sodium):

1 0 HN(CN)2 2. Guanidine: H2N - C(NH) - NH2 3. Guanidine salts: H2N - C(NH) - NH2 . X
where X = HCI or HBr, acetate, carbonate, phosphate, or sulfate;
4. Biguanidine: H2N - C(NH) - NH - C(NH) - NH2 15 5. (C1-C20) Alkyl guanidine or biguanidine, or aryl or alkylaryl guanidine or biguanidine;

6. Dicyandiamide: H2N - C(NH) - NH - CN
and sulfate or acetate salts;

7. Guanylurea: H2N - C(NH) - C(0) - NH2 (or guanyl thiourea) 8. Cyanamide: H2N - CN;
5 9. Guanidine, biguanidine and dicyandiamide and urea (co)polymer;

10. Polycyclic guanidine (see, e.g., Re.34,486 Col.5, Line 65).

The above starting materials are reacted in a high boiling point solvent, in thepresence of an amine, for example, cycloamine, aromatic amine, and hydroxyalkyl amine. The preferred amines are alkyl amines defined by the general formula:

H2N(CH2cH(Y)NH)x H

wherein Y is hydrogen or lower alkyl (C1-C4) and where x is from 1 to 5.
More specifically the (co)polymer of the cyanoguanidine, dicyanimide, guanidine or biguanidine are formed with comonomers of ammonium salt, urea, and alkylamine.

-The most preferred comonomer is alkyl amine as exemplified by ethylenediamine, diethylenetriamine, triethylenetetramine, propylenediamine, methyl or ethyl or butyl alkanolamine, e.g., aminotrihydroxyethylenediamine, monopropanolamine, diethanolamine, crude diaminopropanol and glycolamine. The solvent is selected from high boiling point organic solvents, such as a glycol, optionally in admixture with water.
Hence, the present invention describes the condensation process for preparing non-formaldehyde cationic or multiply cationic charged agents from dicyandiamide or dicyanimide, guanidine or biguanidine, or polymers or (co)polymers thereof, withamine and occasional urea present, in the presence of ammonium chloride, ammonium bromide or ammonium iodide, ammonium sulfate, or ammonium nitrate.
The presence of either the ammonium salt or urea will facilitate the reaction of the -CN group of, for example, the dicyandiamide monomer without cracking, thereby giving better yield and a more uniform product.
Another aspect of the present invention is that the products prepared in accordance with this process, and even the products according to the methods of the patents described above, may be further reacted with the herein described cationic or multiply cationic charged agents, to produce desired cationic polymer or (co)polymeric material.
For Example, the amine and the polyguanidines of the prior art, (for example, U.S. Patent No. 2,649,354; 3,873,266; 4,410,652; 4,439,203; 4,439,208), are 2 ~ 48055 suitable for reaction with chain transfer agents B(a) to B(j) shown below. U.S. Patent Nos. 2,304,369 and 2,945,774 teach the reaction of urea with cationic or anioniccoupling agents from fatty acids, diethylenetriamine, in reaction with quaternization agents. These disclosures are fully incorporated by reference. Another example is U.S. Patent No. 4,410,652, which describes the reaction of guanidine with alkyl amine in situ at 160C. This process is very difficult to carry out on an industrial scale, leads to the cracking and decomposition of the nitrile groups and produces an extremely viscous material, which is a nonionic product. However, such a productcan be used further in the reaction of the present invention with cationic or multiply cationic charged agents. However, the products described above in the prior art patents are very sensitive to bleaching compositions and are susceptible to "bleeding"
and dye discoloration.
In contrast, the cationic polyguanidine or its (co)polymer described by this invention has excellent dye fastness, improved color yield and bleaching composition with little or no dye discoloration. More particularly, the guanidine and/or polyguanidine or a co-polymer thereof is reacted from 25C to 195C, preferably 35C to 165C, in organic solvent or an aqueous medium or an aqueous/organic solvent system with reactive cationic or multiple cationic agents. The reactions may be carried out in the presence of a chain transfer agent, such as 2,2-sulfonyl-bis hyd roxyethyl .

The mole ratio ranges of (I) amine derivative, (Il) ammonium salt and (Ill) guanidine monomer and (IV) occasional urea are as follows:
0.1-2.0 M: 0.5-2.0M: 0.05-2.25 M: 0.25-1.5 M
11 : 111 : lV
5 where ll is an ammonium salt.
When the reaction is carried out in the presence of urea, the mole ratio ranges are:
0.1-1.5 M: 0.25-1.5 M: 0.15-2.5 M: 0.5-2.0 M
ll : lll : IV
10 where ll is ammonium salt.
The general reaction can be written as follows:
Cyanoguanidine/orguanidine derivative + ammonium salt + alkyl amine + solvent ------> polymer/or (co)polymer + DEG + water ----> aqueous (co)polymer, where DEG is diethylene glycol.
15 More preferably, the reactant side of the reaction scheme is as follows:
Cyanoguanidine + Ammonium chloride + diethylenetriamine + diethyleneglycol (DCDA) (NH4CI) (DETA) (DEG) The guanidine, polyguanidine or (co)polyguanidine are formed at pH 4.0 to 1 1 .0 in either free or salts form. These are further reacted with cationic or multiply 20 cationic chain transfer agents. Representative chain transfer agents useful in the practice of the invention have present a substituent which is a halo atom (chlorine, 214~055 bromine, iodine), a sulfate group substituted with methyl or ethyl, methoxy, or ethoxy, or a nitrate anion present.

_ B(l): a mixture of any of (a) through (k), as illustrated, for example, in Re.34,486 Example Nos. 15A, 16A, No.29-44 (steps 1 to 7).

Thus, first ammonium halide, sulfate or nitrate, is reacted with one of dicyanimide or dicyandimide or biguanidine, at 65-195C to form a polyguanidine 5 cation ammonium salt which will further react with alkylamine to generate the desired polymer or (co)polymer. This reaction can be written as follows:
H2N-C(NH)-NH-CN + NH4CI + H2N(CH2CH2N)n H + H20/DEG
(DCDA) (AMC) (DETA) --->[H2N-C(NH)-NH-C(NH)-NH2+]CI-+(H2N-CH2CH2)2NH

m is less than 100,000 When urea is used in addition to the ammonium salt reactant and an amine reactant, the (co)polyguanidine has the following structure:

Secondly, the polyguanidines and (co)polyguanidines are reacted with cationic 10 or multiply cationic charged agents to form improved non-formaldehyde cationic polymeric materials.

The products according to the invention have utility as flame retardants, 5 dispersing agents, antistatic agents, paper sizing, as pitch control agents, in felt cleaner compositions, antimicrobial, precipitant and flocculating agents. The cationic or multiply cationic charged polyguanideines may also be used in combination with 2~ 48055 a sequestering agent such as a phosphonic acid or an aminotricarboxylic acid. The following non-limiting examples demonstrate various aspects of the invention, namely, polymeric and copolymeric products, their preparation and their utility. All parts and percentages are by weight and temperature is expressed in degrees 5 Centigrade.
Example No.1 A 500 ml resin kettle flask was equipped with a condenser, a mechanical stirrer, and a thermometer. To the flask was added diethylene triamine (71.719, 0.695 mole).
The triamine was heated to 55-60 with stirring, followed by the addition of ammonium chloride (44.889, 0.824 mole), added gradually over 20 minutes. The mixture was heated up to 95-100 and then mixed for 15 minutes.
