Abstract
Vinyl chloride-grafted ethylene copolymer superior in adhesiveness both to metals, glasses or polar high molecular materials such as polyamides and to non-rigid vinyl chloride resins is provided in which backbone polymer is copolymer of ethylene, ester of monohydric alcohol of 1-8 carbon atoms with acrylic acid or methacrylic acid and maleic anhydride and pendant or grafting polymer is vinyl chloride polymer. This copolymer is produced by graft-polymerization of vinyl chloride onto the ethylene-acrylic or methacrylic ester-maleic anhydride copolymer.
