Thermoplastic compositions of crystalline polyolefin and ethylene-containing copolymer

摘要

A melt processible multi-phase thermoplastic composition comprising a blend of: (A) 5-95 parts by weight of a crystalline polyolefin resin of a substantially saturated homopolymer or copolymer of polymerized monomer units of C2-C8 alpha monoolefins forming one phase of the composition, (B) 5-95 parts by weight of a crosslinked ethylene-containing copolymer forming a second phase of the composition comprising units derived from (1) ethylene, (2) alkyl acrylates or alkyl methacrylates wherein the alkyl group contains 1-6 carbon atoms or vinyl esters of monocarboxylic acids having 2-6 carbon atoms, and (3) glycidyl acrylate or glycidyl methacrylate.
