Abstract

Description
This invention relates to vinyl resins having bactericidal properties. More particularly, it relates to polyvinyl esters which display marked anti-bacterial and anti-fungal characteristics. Still more particularly, it relates to molded vinyl resins and to plasticizers therefor and to a novel method of incorporating phenoxarsine compounds as a component of the plasticizers.
In accordance with the invention, a solution of a phenoxarsine is prepared, the solution is introduced into a compatible plasticizer and the plasticizer composition incorporated into vinyl resins which will be subjected to mechanical manipulation, i.e., to pressing, swaging, molding, etc., to produce molded objects, flexible sheeting and film, coating compositions, and the like.
In general, resinous materials such as polymers and copolymers of polyvinyl esters are inert to microbial and fungal attack. Nevertheless, they readily act as carriers for microorganisms and the surface of resinous articles may become contaminated with materials which function as nutrients for the microorganisms so that the growth of the latter can occur on such surfaces. In addition to being a continuous source of contamination, the articles themselves are often subject to deterioration due to bacterial and fungal attack on the plasticizers incorporated into the resins to impart certain desirable physical properties and to facilitate molding operations.
It has been common practice, in order to protect resins from bacterial and fungal deterioration to incorporate agents for the purpose of rendering the resinous products bacteriostatic. Most of these agents have suffered from the disadvantage that their solubility in the resins or in the plasticizers were limited, or they were relatively fugitive, as a consequence of which their effectiveness was of limited duration. A further disadvantage has been that the known agents must be used in relatively large concentrations, as for example, 2% to 4% of the resin. This is ordinarily objectionable both from the viewpoint of cost and because the excessive amount of bacteriostat may adversely affect the color or the physical properties of the resin. The method of incorporating the agents capable of imparting bactericidal and fungicidal properties, used hereto, has been to mill in, for example, powdered fungicidal agent or to mix in the resin being compounded, a solution of the agent in such compatible fugitive solvents as toluene, benzene, and the like.
Now, it has been discovered that phenoxarsine compounds which are insoluble in the fugitive solvents commonly available in the plastic industry, for example, glycols such as propylene glycol, ethers such as ethylene glycol monobutyl ether, ketones such as ethyl methyl ketone, diisobutyl ketone, etc., and the like and also insoluble in plasticizers such as, dioctyl phosphate, tricresyl phosphate, epoxidized tallate, butyl phthalyl butyl glycolate, ethyl salicylate, and the like, can be incorporated in effective small amounts in a unique solution form compatible with the plasticizers to provide the compositions with excellent anti-bacterial and anti-fungal properties. The phenoxarsine compounds when incorporated by this phenol solvent solution method display an effective microbicidal and fungicidal action rather than a mere inhibition of the growth of such bacteria.
As above indicated, relatively small amounts of the phenoxarsine component, i.e., amounts of the order of 100 to 500 parts per million, present in the resinous compositions in a solution form are effective to produce the desired effect.
The phenoxarsine compounds to be employed in accordance with the present invention have the following general formula: ##STR1##
Derivatives of the phenoxarsines useful in the instant invention are, for example, the halogen derivatives such as 10-chlorophenoxarsine, 10-iodo-phenoxarsine, 10-bromo-phenoxarsine, 4-methyl-10-chlorophenoxarsine, 2-tertiary butyl-10-chlorophenoxarsine, 1,4-dimethyl-10-chlorophenoxarsine, 2-methyl-8,10-dichloro phenoxarsine, 1,3,10-trichloro phenoxarsine, 2,6,10-trichloro phenoxarsine, 2,8,10-trichloro phenoxarsine, 1,2,4,10-tetrachloro phenoxarsine, the oxygen derivatives such as the 10,10'-oxybis phenoxarsine, the thio derivatives such as 10-thiocyanato phenoxarsine, 10,10'-thio bis phenoxarsine, also may be used.
These phenoxarsine compounds are prepared for incorporation into a plasticizer and subsequent incorporation into the resins by dissolving in hydroxy-bearing solvents in which the compounds are soluble to the extent of at least 5%. Generally, the phenoxarsines have a higher solubility in compounds such as phenols and the combination of phenoxarsine and the phenols are preferred because quantities of phenoxarsines of the order of 300 to 500 parts per million are obtainable with lesser quantities of the solvent phenols which phenols cannot be tolerated in, for example, vinyl resins in too great a proportion.
Materials useful as a solvent for the phenoxarsine compounds are those having a labile hydroxyl group. Useful compounds are mono and di-hydroxy compounds, for example, phenol, phenol derivatives, for example, the alkyl phenols, such as cresols, e.g., methyl phenol, 2-methyl-5-isopropyl phenol, 3-methyl-6-isopropyl phenol, and the like. Chlorinated phenols such as 4-chloro-2-phenylphenol, and 6-chloro-2-phenylphenol. Amino phenols such as p-aminophenol and m-aminophenol. Dihydric phenols such as catechol, resorcinol, 3,5, dihydric toluene, and the like, aliphatic alcohols having 5 to 12 carbon atoms such as lauric, 2-ethyl hexanol, octenol, 1,2,6-hexantriol, 2-methoxy methyl-2,4, dimethyl pentane diol, and the like, and monocarbocyclic acid having 5 to 12 carbon atoms such as caproic acid, 2-ethyl hexoic acid, isotoic acid, and the like. The solvent carrier compatible with the plasticizers which is preferred, is a non-toxic alkyl phenol, such as nonyl phenol, dodecyl phenol, di-sec amyl phenol, and the like.
The solution of phenoxarsine in a solvent containing a labile hydroxyl group is incorporated into a plasticizer for the resin to be mechanically worked. Typical plasticizers are tricresyl phosphate, dipropylene glycol, dibenzoate, diphenylcresyl phosphate, epoxidized soya, epoxidized tallate, dioctyl azelate, alkyl aryl phosphates, diisobutyl phthalate, hydrogenated methyl rosin ester, and the like.
The solvent solutions of phenoxarsine which are preferred, are those which hold in stable solution between about 10% and about 25% by weight of arsenical although amounts of arsenical as low as 5% may be used. Such a solution can be dissolved and/or dispersed in the plasticizer in amounts constituting between about 2% and about 10% by weight of the total mixture, with amounts in the range between about 4% and about 6% preferred. The plasticizer compositions thus contain between about 0.2% and 2.5% of phenoxarsine compound, between about 1.8% and 7.5% of solvent and between about 90% to 98% of plasticizer.
When phenoxarsines are present in a plasticizer in the quantity set forth, the phenoxarsine content of a processed resin, for example, vinyl resin, will be in the range between about 0.02% and about 0.1%, i.e., amounts in the range between about 200 and 1000 parts per million.
In order to more fully illustrate the invention, the following examples are included. These examples are intended to be illustrative and are given without any intention that the invention be limited thereto.
