MODIFIED POLYSTYRENIC FOAMABLE RESIN PARTICLES, METHOD FOR MANUFACTURING THE SAME, FOAM PARTICLES, AND FOAM MOLDING

摘要

PROBLEM TO BE SOLVED: To provide modified polystyrenic foamable resin particles affording a significantly abbreviated aging period in days and resistant to heat chaps during a high-temperature storage; a method for manufacturing the same; foam particles; and a foam molding.SOLUTION: The problem-solving modified polystyrenic foamable resin particles are modified polystyrenic foamable resin particles including: a polystyrenic resin; a polyacrylic acid alkyl ester resin; a foaming agent; and an aging accelerator wherein the polyacrylic acid alkyl ester resin exists within the polystyrenic resin as particulates having an average particle diameter of 30-1000 nm and wherein the aging accelerator is a hydroxy fatty acid amide.
