Abstract
Abstract This invention involves terpolymers of vinyl chloride, vinyl acetate and hydroxyalkyl acrylate wherein there is incorporated about 2.00 to about 5.5% by weight of the latter two monomers. These polymers provide efficacious protective coatings capable of forming a particularly effective adhesive bond to metallic substrates.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A thermoplastic resinous adhesive composition capable of forming a protective barrier for and adhering effectively to similar and dissimilar substrates comprising a resin plasticized with 35 to 150 parts of a plasticizer per 100 parts of the resin, said resin has a particle size of 25 to 150 microns, a relative viscosity of 1.55 to 2.00 measured at 25° C of 1% resin in cyclohexanone and is prepared from 2.00 to 5.5% by weight of hydroxyalkyl acrylate where the alkyl group contains from 1 to 4 carbon atoms, from 2.00 to 5.5% by weight of vinyl acetate, and from 96.0 to 89.0% by weight of vinyl chloride, the amounts being based on weight of monomers used in preparing said resin.
Claim 2
Dependent Claim
120 words
A thermoplastic resinous adhesive composition capable of forming a protective barrier for and adhering effectively to similar and dissimilar substrates comprising a resin plasticized with 35 to 150 parts of a plasticizer per 100 parts of the resin, said resin has a particle size of 25 to 150 microns, a relative viscosity of 1.55 to 2.00 measured at 25° C of 1% resin in cyclohexanone and is prepared from 2.00 to 5.5% by weight of hydroxyalkyl acrylate where the alkyl group contains from 1 to 4 carbon atoms, from 2.00 to 5.5% by weight of vinyl acetate, and from 96.0 to 89.0% by weight of vinyl chloride, the amounts being based on weight of monomers used in preparing said resin.
Claim 3
Dependent Claim
31 words
