STYRENE MODIFIED POLYETHYLENE BASED RESIN PREFOAMED PARTICLE, AND FOAM FORMED OF THE PREFOAMED PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide styrene modified polyethylene based resin prefoamed particles hardly causing mutual sticking of polyethylene-based resin particles during polymerization. SOLUTION: The styrene modified polyethylene based resin prefoamed particles are obtained by foaming styrene modified polyethylene based resin particles with polyethylene-based resin particles impregnated and polymerized with a styrene-based monomer by adding the styrene-based monomer into an aqueous suspension containing polyethylene-based resin particles, wherein the polyethylene-based resin particles comprise an ethylene-vinyl acetate copolymer with the vinyl acetate content of 3-7 wt.%, a melt flow rate of 0.3-1.0 g per 10 minutes and a fusing point of 95-104°C.
