Abstract

Shaped articles are made by shaping at elevated temperatures a uniform mixture of a polymer of vinyl chloride, one or more monoethylenic monomers which are compatible with the polymer and a thermal polymerization inhibitor, and subjecting the shaped mixture to high energy ionizing radiation. The examples describe homogenizing mixtures of polyvinyl chloride and styrene containing dinitro-o-cresol or tertiary butyl-catechol, moulding the mixtures, and irradiating them with X-rays. Specifications 996,641 and 996,642 are referred to.
