Abstract

Interpolymer resin particles comprised of 20% to 80% by weight polyolefin, e.g.polyethylene and 80% to 20% by weight of an in situ polymerized vinyl aromatic resin, e.g. polystyrene or poly(styrene.butyl acrylate) and forming an interpenetrating network of polyolefin and vinyl aromatic resin particles.
The interpolymer particles are impregnated with a volatile hydrocarbon blowing agent, and limonene, e.g. d-limonene, ranging from about 0.1 to about 5 parts, preferably 0.1 to 1 part by weight, based on 100 parts by weight of the interpolymer particles, for improved expandability and a pleasant fragrance.
