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.
