Abstract

PURPOSE: To obtain a blowing composition capable of forming a foamed material having a rapid crosslinking rate, uniform cells, excellent strength, excellent wear resistance, and excellent heat resistance, by adding a crosslinking agent and a blowing agent to a specific polyolefin.
CONSTITUTION: One hundred pts.wt. ethylene-alpha-olefin copolymer, obtained from the gas-phase polymerization of ethylene and an alpha-olefin (e.g., butene-1) in the presence of a catalyst composed of a combination of a solid catalyt component prepared by supporting a titanium compound and/or a vanadium compound on an inorganic solid support (e.g., MgO-RX-TiCl4, wherein R is an organic group and X is a halogen) and an organic aluminum component, and having a desnsity of 0.89W0.945 and a melt index of 0.1W10, is mixed with 0.05W10pts.wt. crosslinking agent (B) (e.g., dicumyl peroxide) and 1W50pts.wt. blowing agent (C) (e.g., azodicarbonamide).
