Abstract

Expanded mouldings made of P.V.C. or of vinyl chloride copolymers are produced by impregnating the starting material with a porogenic agent or a mixture of a porogenic agent and a blowing agent, followed by dissolution and foaming of the polymer, the starting material being in the form of pearls or granules and the impregnated material being placed in a mould where it is foamed by the action of heat, in a single stage, to obtain the desired moulding.
