Production manner null of foaming Characteristic rubber denaturation styrene type resin

摘要

PURPOSE: To provide a process for producing expandable rubber-modified styrene resin particles suitable for obtaining a molded foam excellent in surface appearance, impact resistance, and flexibility. ;CONSTITUTION: In the process for producing expandable rubber-modified styrene resin particles by dispersing rubber-modified styrene resin particles in an aq. medium in a hermetically sealed container and impregnating the particles with a volatile blowing agent, at least the impregnation is conducted in the presence of an electrolyte in a concn. of 0.01-2.0mol/l (based on the medium).;COPYRIGHT: (C)1996,JPO
