EXPANDABLE POLYSTYRENE-BASED RESIN PARTICLE, MANUFACTURING METHOD THEREFOR, POLYSTYRENE-BASED RESIN PRE-EXPANDED PARTICLE, AND POLYSTYRENE-BASED RESIN EXPANSION MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide expandable polystyrene-based resin particles capable of manufacturing a polystyrene-based resin expansion molded article with a small amount of a remaining styrene-based monomer being excellent in heat-insulation property and mechanical strength.;SOLUTION: In the expandable polystyrene-based resin particles, a foaming agent is included in a resin particle containing a copolymer of a hydroxyl group-containing monomer and a styrene-based monomer. As the hydroxyl group-containing monomer, at least one hydroxyl group-containing monomer selected from the group consisting of an acrylate having a hydroxyl group in the molecule and a methacrylate having a hydroxyl group in the molecule is preferable.;COPYRIGHT: (C)2011,JPO&INPIT
