Abstract
Abstract An adhesive composition for bonding polished metal surfaces to vinyl chloride polymer coated metal substrates is disclosed which is comprised of a thermoplastic vinyl chloride polymer resin, a thermosetting epoxy resin normally incompatible with the vinyl chloride polymer resin and an amount of an acrylonitrile/butadiene/styrene copolymer which imparts compatibility between the epoxy resin and the vinyl chloride polymer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
An adhesive composition comprising a volatile organic solvent having dispersed therein about 10 to about 70% by weight of a thermoplastic vinyl chloride polymer resin and about 5 to about 30% by weight of a thermosetting epoxy resin normally incompatible with the vinyl chloride polymer resin and an amount of about 20 to about 85 percent by weight of an acrylonitrile/butadiene/styrene copolymer which amount of copolymer is capable of imparting compatibility between the epoxy resin and the vinyl chloride polymer, the copolymer containing about 10 to about 30% by weight acrylonitrile, about 10 to 30% by weight butadiene and about 40 to about 70 percent by weight styrene.
Claim 2
Dependent Claim
108 words
An adhesive composition comprising a volatile organic solvent having dispersed therein about 10 to about 70% by weight of a thermoplastic vinyl chloride polymer resin and about 5 to about 30% by weight of a thermosetting epoxy resin normally incompatible with the vinyl chloride polymer resin and an amount of about 20 to about 85 percent by weight of an acrylonitrile/butadiene/styrene copolymer which amount of copolymer is capable of imparting compatibility between the epoxy resin and the vinyl chloride polymer, the copolymer containing about 10 to about 30% by weight acrylonitrile, about 10 to 30% by weight butadiene and about 40 to about 70 percent by weight styrene.
Claim 3
Dependent Claim
14 words
