摘要

PROBLEM TO BE SOLVED: To provide a styrene-modified polypropylene-based resin foamed molded product excellent in mechanical properties and chemical resistance, etc., by modifying weak points of both of a polystyrene-based resin foamed molded product and a polypropylene-based resin foamed molded product.;SOLUTION: A method for producing the styrene-modified polypropylene-based resin product comprises a first polymerization process for carrying out the first polymerization of a styrene-based monomer at a temperature range of (T-10) to (T+20)C, wherein the melting point of the polypropylene-based resin is TC, and a process for, following the first polymerization process, adding the styrene-based monomer and a polymerization initiator thereto and performing impregnation of the styrene-based monomer to the polypropylene-based resin particles and a second polymerization process at a temperature of (T-25) to (T+15)C.;COPYRIGHT: (C)2011,JPO&INPIT
