The crosslinking of internally plasticized polyvinyl chloride- stearate copolymer by irradiation with high-energy electrons was studied. Based on gel yields and swelling as a measure of relative crosslinking, the effect of added tetrafunctional monomers, and of carbon black and silica fillers are discussed. Crosslinking by dicumyl peroxide at 170 deg C even in the presence of a stabilizer, causes concurrent decomposition (dehydrochlorination) which is avoided in the radiation crosslinking process. The heat sthbility of the copolymer is not impaired by radiation crosslinking under the proper conditions. Results of tensile measurements at 25 and l50-C are given for the radiation crosslinked copolymer with and without filler reinforcement. (auth)
