DETAILED DESCRIPTION OF THE INVENTION
In accordance with the invention, novel oxime- blocked isocyanaytes based on TMI® (META) unsaturated aliphatic isocyanate* (hereinafter referred to as "TMI isocyanate") have been discovered. TMI isocyanate is a known material which is commercially available through American Cyanamid Co. Alternately, it may be synthesized by known techniques.
*Phys cal properties: TMI isocyanate appearance: colorless liquid molecular formula : C13H15NO molecular weight: 201.26
NCO content: 20.9% (theoretical) boiling point: 270"C (latm) vapor pressure: 2mm Hg (100°C) viscosity: 3 cp (27°C) density: 1.01 g/ml solubility: vinyl monomers, most common solvents
TMI isocyanate is a bifunctional monomer containing a tertiary aliphatic isocyanate group and a reactive double bond.
The novel oxime-blocked TMI isocyanates of this invention may be prepared by reacting TMI isocyanate with the appropriate oxime.
When the oxime is methyl isobutyl ketoxime, R and R1 comprise a methyl and isobutyl group respectively and the resulting oxime-blocked TMI isocyanate is methyl isobutyl ketoxime-N-(m-isopropenyl-α, α-dimethyl benzyl) carbamate. Similarly, when the oxime is methyl and amyl ketoxime, R and R1 comprise a methyl group and amyl group respectively and the resulting oxime-blocked TMI isocyanate is methyl amyl ketoxime-N-(m-
isopropenyl-α, α-dimethyl benzyl) carbamate. When the oxime is di-isobutyl ketoxime, R and R1 each comprise an isobutyl group and the resulting oxime-blocked TMI isocyanate is di-isobutyl ketoxime-N-(m-isopropenyl-α, α-dimethyl benzyl) carbamate. Similarly, when the oxime is di-isopropyl ketoxime, R
and R1 each comprise an isopropyl group and the resulting oxime-blocked TMI isocyanate is di-isopropyl ketoxime-N-(m-isopropenyl-α, α-dimethyl benzyl) carbamate. A detailed synthesis of these compounds may be found in Examples 1-4 below.
EXAMPLE 1
Preparation of methyl isobutyl ketoxime-N-(m- isopropenyl-α, α-dimethyl benzyl) carbamate. To a one liter 3-necked flask equipped with a thermometer, agitator and nitrogen gas purge was added 306 grams of TMI and 5 drops of dibutyltin dilaurate. The mixture was then heated to 90°C. To this mixture, 179 grams of methyl isobutyl ketoxime was added dropwise over a 15 minute period maintaining the reactor temperature at about 90-100°C. After addition of the methyl isobutyl ketoxime, the reaction was held at about 100-105"C for 30 minutes with continued agitation. The product was poured into paint cans for storage. 425 grams of product were obtained for an 87.6% yield. The product -oxime-blocked TMI isocyanate ahd the following properties:

To a one liter 3-necked flask equipped with a thermometer, agitator and nitrogen purge gas was added 300 grams of TMI and 5 drops of dibutyltin dilaurate. The mixture was then heated to about 90°C. To this mixutre was added 197 grams of methyl amyl ketoxime dropwise over a 20 minute period with minimum cooling. After addition of the methyl amyl ketoxime, the reaction was held at about 100-105°C for 30 minutes with continued agitation. The product was poured into paint cans for storage. 445 grams of product were obtained for an 89.5% yield. The properties of the product oxime blocked TMI were as follows:
Free NCO content, % - 0
Color (APHA) - 30 Viscosity (Gardner-Holdt) - L-M
Equivalent wieght (calc.) - 331
EXAMPLE 3

To a one liter 3-necked flask equipped witha thermometer, agitator and nitrogen purge is added 301 grams of TMI isocyanate and 5 drops of dibutyltin dilaurate and the mixture is heated to 90°C. To this mixutre is added 197 grams of di-isopropyl ketoxime dropwise over a 20 minute period with minimum cooling. After addition of the di-isopropyl ketoxime, the reaction is held at 100- 105°C for 30 minutes with continued agitation. The
product is poured into paint cans for storage. The equivalent weight of the product is 330.
EXAMPLE 4
Preparation of di-isobutyl ketoxime-N-(m- isopropenyl-α, α-dimethyl benzyl) carbamate. To a
one liter 3-necked flask equipped with a thermometer, agitator and nitrogen purge, is added 301 grams of TMI isocyanate and 5 drops of dibutyltin dilaurate and the mixture is heated to 90°C. To this mixutre is added 240 grams of di-isobutyl ketoxime dropwise over a 20 minute period with minimum colling. After addition of the di-isobutyl ketoxime, the reaction is held at 100- 105°C for 30 minutes with continued agitation. The product is poured into paint cans for storage. The equivalent weight of the product is 358.
The novel oxime-blocked TMI isocyanates of this invention may be blended together or with other known oxime-blocked TMI isocyanates depending on the properties desired. For example, blends may be used to improve the working viscosity during polymerization reactions with other reactants or to increase the solids content in order to reduce the level of volatile organic components. The blends may be prepared in situ or by physically blending the oxime-blocked isocyanates together. The oxime-blocked TMI isocyanates may be combined in any proportions.
Oxime-blocked TMI isocyanates are unqiue molecules. The double bond in the oxime blocked TMI isocyanate undergoes free radical polymerization
readily with various unsaturated monomers yielding copolymers with pendant, isocyanate functionality.
