Abstract

PURPOSE: To obtain the title foam having improved dimensional stability, surface smoothness, etc. by foaming a blend of a specific amide, a blowing agent, and a polyolefin resin without using a specific blowing agent.
CONSTITUTION: (A) A polyolefin resin is blended with (B) preferably 0.4W 10 wt.% of an amide, e.g. a prmary amide, preferably lauric acid amide, etc., of formula I: (R1 is 8W21C saturated hydrocarbon group; R2 and R3 are H or 1W22C saburated hydrocarbon groups), formula II: (R4 and R5 are 8W21C saturated hydrocarbon group; R6 is H or 1W22C saturated hydrocarbon group), and/or formula III: (R7, R8, and R9 are 8W21C saturated hydrocarbon groups) and (C)a blowing agent, preferably a volatile organic blowing agent. The blened is then foamed by heating to give the desired foam.
EFFECT: Scarcely causing shrinkage with time
