Radiation crosslinking of PVC in the presence of triallyl cyanurate as a sensitizer, dioctyl phthalate as a plasticizer and lead and tin stabilizers was examined. Standard methods of testing PVC materials were used. Direct relations between crosslinking extent, elongation, and Vicat softening temperature changes were found. Lead stabilizers proved to be more efficient than tin stabilizers. The influence of radiation dcse on immediate and long‐term changes of PVC was investigated.
