Abstract

Process for obtaining cellular vinyl chloride polymers, characterized in that at least one vinyl chloride polymer is mixed with a chemical system that produces expansion, consisting of at least one nitrogenous derivative of carbonic acid and at least one acid carboxylic having 3 to 18 carbon atoms and chosen from the group consisting of aliphatic saturated acids substituted or not by at least one cyano, chlorine, bromine, alkyl, aryl, aryloxy or chloroaryloxy group and cycloaliphatic saturated acids; it gels, conforms and undergoes expansion.
