Abstract
1. A process for obtaining a polyolefin resin foam, comprising the steps of dispersing a blowing agent composition comprising (a) azodicarbonamide, (b) dinitrosopentamethylene-tetramine, and (c) a phenolic antioxidant, or (b) ) hexamethylenetetramine in place of said components (b) and (c), in a polyolefin resin to form an expandable resin preform; introduce a crosslinking structure into it; and expanding said preform by heating at normal pressure, either after introducing the crosslinking structure into said preform, or in the course of introducing the crosslinking structure therein.
