Abstract

An adhesion assistant or binder composition for bonding polyolefin surfaces with metal surfaces comprising an aqueous dispersion of an ethylene/vinyl acetate copolymer from 0.5 to 5 parts by weight based on 100 parts of the copolymer of a cross-linking peroxide compound and from 1 to 10 parts by weight based on 100 parts of the copolymer of a low-molecular-weight 1,2-polybutadiene; as well as a process for producing composite bodies by heat and pressure utilizing the above adhesion assistant between polyolefin surfaces and metal surfaces.
