EXPANDABLE RESIN BEADS OF STYRENE-MODIFIED, STRAIGHT -CHAIN, AND LOW-DENSITY POLYETHYLENE, PROCESS FOR PRODUCTION THEREOF, PRE-EXPANDED BEADS, AND FOAMS

摘要

Expandable resin beads of styrene-modified, straight -chain, and low-density polyethylene, which comprise both a base resin obtained by blending a non-crosslinked, straight-chain, and low-density polyethylene resin component with a polystyrene resin component in an amount exceeding 300 parts by weight and up to 1000 parts by weight per 100 parts by weight of the polyethylene resin component and a volatile foaming agent and in which the base resin contains 2 to 40 wt% of a gel consisting of a graft polymer composed of the low-density polyethylene resin component and the polystyrene resin component.
