Expandable resin beads of styrene-modified straight-chain and low-density polyethylenne, process the production thereof, pre-expanded beads, and foams

摘要

According to the present invention, there is provided expandable particles of a styrene-modified linear low-density polyethylene-based resin comprising a volatile blowing agent and a base resin, the base resin containing more than 50 to 1000 parts by weight of a polystyrene-based resin component relative to 100 parts by weight of a non-crosslinked linear low-density polyethylene-biased resin component, wherein the base resin contains less than 2 wt % of a gel component comprising a graft polymer of the polystyrene-based resin component and the low-density polyethylene-based resin component.
