Abstract
A polymer particle is provided comprising a rubbery polymer and a methacrylic glassy polymer as formed in latex interpenetrating polymer networks structure, which is prepared by swelling a rubbery polymer with a swelling solvent and carrying out an emulsion polymerization reaction of methacrylic monomers in the presence of said swollen rubbery polymer. Also provided are a resin composition comprising the polymer particles, such as poly (alkylene terephthate) resin melt-blended with the polymer particles, and a molded article of the resin composition. The molded article has a high impact-strength.
Claims11
A polymer particle comprising (1) a rubbery polymer core comprised of conjugated diene elastomers, C.sub.2-8 alkyl acrylate elastomers or mixtures thereof and (2) a methacrylic glassy polymer shell as formed in latex interpenetrating polymer networks, which is formed by swelling 100 parts by weight of the rubbery polymer with 10 to 200 parts by weight of a swelling solvent wherein the swelling solvent is miscible with methacrylic monomers and carrying out an emulsion polymerization reaction of the methacrylic monomers in the presence of the resultant swollen rubbery polymer.
