Abstract

Procedure for the preparation of cellular products, based on polymers of vinyl chloride, characterized in that at least one polymer of vinyl chloride is mixed with a chemical system that produces expansion, consisting of at least one nitrogenous derivative of carbonic acid and of at least one unsaturated acid having 31 to 12 carbon atoms and chosen from the group consisting of aliphatic acids having alpha or beta of an ethylenic or acetylenic bond and substituted or not by at least one halogen atom, a lower alkyl, phenyl or phenoxy group and by aryl acids substituted or not by at least one alkyl group or a halogen atom; it gels, conforms and undergoes expansion.
