Abstract
A method of producing molded articles from polyolefin molding compositions crosslinked by irradiation, to which molding composition is added, prior to irradiation, by mixing and/or copolymerizing, from 0.3 to 20 percent by weight of vinylacetate, optionally in a form as pre-copolymerized with a polyolefin. The occurence of undesirable accumulations and discharges of electrical charge concentrations and/or the undesirable foaming of the polyolefin molded articles will thus be suppressed.
