Date Jun. 27, 1991.A method for production of a crosslinked, foamed vinyl chloride containing polymer, by adding a blowing agent to a copolymer produced by a copolymerisation of a monomer composition comprising vinyl chloride and glycidyl containing monomer, and optionally other monomers, foaming the copolymer, where the decomposition products of the blowing agent or decomposition products of reaction produces from the blowing agent, are chemically reactive with epoxy groups of the copolymer or its reaction products, and crosslinking the copolymer when the blowing agent or the reaction product of the blowing agent is decomposed.
