Paintable high specific adhesion polyvinyl halide copolymer compositions
摘要:
Flexible or semi-rigid articles are formed from copolymers of vinyl halide monomers and an adhesion-promoting comonomer are directly painted. The invention also pertains to an article consistng of a metal, plasic or wood component placed in intimate contact with the melt-processed PVC copolymer composition, intimate contact occurring in the melt state, said copolymer comprising preferably 40-60 parts by weight of a vinyl halide monomer per 100 weight parts copolymer and a (meth)acrylate adhesion-promoting comonomer, said copolymer exhibiting high specific adhesion to polar metals and polar polymer substrates.
