Polyvinyl chloride is bonded to natural or synthetic elastomers by means of a solution grafted copolymer of an acrylic monomer and a synthetic elastomer. If the elastomer is natural rubber or a sulphur modified chloroprene elastomer, a solution grafted copolymer of methyl methacrylate, butadiene and preferably also acrylonitrile, is used. If the elastomer is a non-sulphur modified chloroprene rubber, a solution grafted copolymer of methyl methacrylate and chloroprene rubber is used.
