ABSTRACT:
An expanded polyvinyl chloride foam is prepared by a process characterized by admixing a polyvinyl chloride resin, which is prepared by emulsion copolymerization of a comonomer having an hydroxyl group, or a group capable of producing an hydroxyl group in the molecule under the processing conditions, with a plasticizer, a cross-linking agent, and a chemical blowing agent, introducing the admixture into a mold at a temperature lower than the melting temperature of said resin, and thereafter heating the resulting molded product to a temperature higher than the melting temperature of said resin to effect foam expansion.
