Abstract
Abstract Adhesives suitable for preparing laminates of polyvinyl chloride or polyvinyl chloride copolymers with wood or metal are prepared from a three component polymer mixture of polyvinyl chloride or its copolymers itself, a direct ethylene copolymer preferably containing units derived from carbon monoxide, and another direct ethylene copolymer containing units derived from a monomer containing glycidyl units. The adhesive is especially useful for preparing PVC/wood laminates which are subject to outdoor weathering.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
An adhesive for polyvinyl chloride and polyvinyl chloride copolymers, comprising: a) 5-65 weight percent of polyvinyl chloride or a polyvinyl chloride copolymer; b) 15-75 weight percent of a first ethylene copolymer, said first copolymer being a direct copolymer containing 30-95 weight percent ethylene, and (i) 0-50 weight percent of a moiety derived from a comonomer consisting of at least one alkyl acrylate, alkyl methacrylate, alkyl vinyl ether, vinyl acetate or mixtures thereof, where the alkyl radical contains 1-8 carbon atoms, and also containing (ii) 1-20 weight percent of a moiety derived from a comonomer consisting of carbon monoxide or sulfur dioxide, provided that (i) is present to an extent equal or greater than [50-(10×(ii)] weight percent, and c) 2-25 weight percent of a second direct ethylene copolymer containing from 0-50 weight percent of a moiety derived from at least one alkyl acrylate, alkyl methacrylate, alkyl vinyl ether, vinyl acetate or mixtures thereof, where the alkyl radical contains 1-8 carbon atoms, and also contains 1-15 weight percent of a moiety derived from glycidyl acrylate, glycidyl methacrylate or glycidyl vinyl ether.
Claim 2
Dependent Claim
179 words
An adhesive for polyvinyl chloride and polyvinyl chloride copolymers, comprising: a) 5-65 weight percent of polyvinyl chloride or a polyvinyl chloride copolymer; b) 15-75 weight percent of a first ethylene copolymer, said first copolymer being a direct copolymer containing 30-95 weight percent ethylene, and (i) 0-50 weight percent of a moiety derived from a comonomer consisting of at least one alkyl acrylate, alkyl methacrylate, alkyl vinyl ether, vinyl acetate or mixtures thereof, where the alkyl radical contains 1-8 carbon atoms, and also containing (ii) 1-20 weight percent of a moiety derived from a comonomer consisting of carbon monoxide or sulfur dioxide, provided that (i) is present to an extent equal or greater than [50-(10×(ii)] weight percent, and c) 2-25 weight percent of a second direct ethylene copolymer containing from 0-50 weight percent of a moiety derived from at least one alkyl acrylate, alkyl methacrylate, alkyl vinyl ether, vinyl acetate or mixtures thereof, where the alkyl radical contains 1-8 carbon atoms, and also contains 1-15 weight percent of a moiety derived from glycidyl acrylate, glycidyl methacrylate or glycidyl vinyl ether.
