ABSTRACT:
A graft copolymer based on ultrahigh-molecular-weight polyethylene having a molecular weight .gtoreq. 1,000,000 g/mol, an ethylene copolymer and a graft monomer; and the preparation and use thereof. The ethylene copolymer contains ethylene and vinyl acetate or ethylene and an alkenecarboxylic acid ester. The graft monomer is an alkenecarboxylic acid or an alkenecarboxylic anhydride. The resultant graft polymers posses improved properties compared with the materials from which they are derived.
