Abstract

PURPOSE:To obtain the title foam having a large cross section, and excellent air permeability, uniform density distribution, cushioning properties, anti-blocking characteristics, weatherability and so on, by extrusion-foaming a mixed resin of a polybutene-1 resin and an ethylene ionomer resin with a specific mixing ratio in the presence of a volatile org. foaming agent. CONSTITUTION:A mixed resin consisting of 100pts.wt. polybutene-1 resin and 10-100pts.wt. ethylene ionomer resin whose supercooling temp. measured by means of D.S.C. are 10-90 deg.C respectively is mixed with 5-50pts.wt. volatile org. foaming agent (e.g. dichlorodifluoromethane) based on the total amt. of the resin, a nucleating agent (e.g., talc) and, if necessary, a lubricant, a foam stabilizer, an ultraviolet stabilizer and so on, and the mixt. is kneaded and melted at high temp. and under high pressure and extruded into a low-temp. and low-pressure zone and foamed there to obtain the title foam whose density is 10-50kg/cm<3>, cross-sectional area is >=150cm<2>, air permeability is less than 10cm Hg, compressional residual strain is less than 20%.
