Quantum yields of dehydrochlorination and of main chain scission were determined for photolysis of PVC in solution in tetrahydrofuran and 1,2-dichloroethane. The observed auto-accelerated degradation results from an increased absorption of light by the growing polyene structures. The presence of oxy
