Polyvinyl chloride plasticized with dioctyl phthalate is cross linked by irradiation with high-energy electrons at doses of 20 x 10/sup 6/ r and above. The product has lower thermal stability against discoloration (dehydrochlorinatio) at 150 deg C than unirradiated material. This impairment can be prevented by adding a small amount of a tetrafunctional monomer, such as a dimethacrylate, prior to irradiation. In the presence of this additive a much lower irradiation dose (about 1 x 10/sup 6/ r) is required to produce cross linking and increased tensile strengths. Radiation cross linking is also effective in the presence of carbon-black filler. Although cross linking increases tensile strength of plasticized polyvinyl chloride even at room temperature, at 150 deg C tensile strength is increased four- or fivefold by irradiation at 1 x 10/sup 6/, for carbon-loadings up to 34%.
