ABSTRACT:
An ethylene-acrylic acid ester copolymer can be easily grafted in a high graft efficiency with a peroxy group-containing block copolymer consisting of segments of copolymer A, which is a copolymer of a (meth)acrylic acid ester monomer or its mixture with a radically copolymerizable monomer, with a radically copolymerizable peroxycarbonate, and segments of (co)polymer B, which is different from copolymer A in the monomer composition and does not contain a monomer unit of the radically copolymerizable peroxycarbonate. The grafted ethylene-acrylic acid ester copolymer can be effectively used as a compatibilizing agent in a polymer blend of polyolefin with styrene (co)polymer, as an emulsifying agent in an emulsion of high polymer, or as an adhesive at the interface of polyolefin and styrene (co)polymer.
