Abstract
In the production of expanded polymerization products the starting material is, after the incorporation of the blowing agent but prior to expansion, subjected to the action of high energy electrons, X-rays, gamma rays or equivalent ionizing radiation. The polymer may be polyethylene, polyvinyl chloride, nylon, polyvinyl acetate or a polyalkyl acrylate, and the blowing agent may be azodicarbonamide, p,p1oxy-bisbenzene-sulphonhydrazide or dinitrosopentamethylene tetramine, expansion being effected by heating.ALSO:In the production of expanded polymerization products the starting material is, after the incorporation of the blowing agent but prior to expansion, subjected to the action of high energy electrons, X-rays, gamma rays or equivalent ionizing radiation.
