Abstract:
1. A polyolefin-based thermoplastic polymer composition comprising an acrylate copolymer phase comprising an acrylate copolymer of an alkyl acrylate monomer, an alkyl methacrylate monomer, and a polar group-containing acrylate monomer; and a polyolefin phase comprising a blend of a polyolefin and at least one polyethylene copolymer, wherein the acrylate copolymer phase is dispersed in the polyolefin phase, wherein the polyethylene copolymer comprises at least one selected from the group consisting of poly(ethylene-co-methylacrylate), poly(ethylene-co-ethylacrylate), poly(ethylene-co-butylacrylate), poly(ethylene-co-acrylic acid), poly(ethylene-co-methacrylic acid), poly(ethylene-co-glycidyl methacrylate), poly(ethylene-co-maleic acid), poly(ethylene-co-vinyl acetate), poly(ethylene-co-acrylamide), and poly(ethylene-co-acrylonitrile); and wherein the amount of the alkyl acrylate monomer is 65-455 parts by weight based on 100 parts by weight of the polyolefin phase, the amount of the alkyl methacrylate monomer is 15-240 parts by weight based on 100 parts by weight of the polyolefin phase, and the amount of the polar group-containing acrylate monomer is 15-300 parts by weight based on 100 parts by weight of the polyolefin phase.
