Abstract

Improved procedure for obtaining fine-cell foamed plastics, from a polymer based on an α, β- monoolefinically unsaturated monomer, by peroxy crosslinking and foaming with a chemical propulsion agent, characterized in that in addition to said peroxide and said Propelling agent a highly dispersed amphoteric oxide is added to said polymer, the mixture thus obtained is subjected to the shaping process and is crosslinked and foam by heating at temperatures of at least 190ºC.
