Abstract

PURPOSE: A composition capable of providing foam having uniform porous structure, hard surface, improved tensile strength and elongation, obtained by blending an ethylene copolymer prepared by high-pressure radical polymerization with a specific ethylene/α-olefin copolymer and a blowing agent.
CONSTITUTION: An ethylenic polymer comprising about 80W50wt% ethylene copolymer obtained by high-pressure radical polymerization and about 20W 50wt% copolymer of ethylene and 3W8C α-olefin having a gravity of 0.91W 0.95g/cm2 is blended with a blowing agent uniformly. A vinyl acetate-containing copolymer is preferable as the ethylene copolymer, and 6W28wt% ethylene-vinyl copolymer is used. The crosslinking carried out simultaneously with the expansion molding is done by adding a chemical crosslinking agent to the blend and heating it at its decomposition temperature.
