摘要：
Photooxidative degradation and photocrosslinking of poly(vinyl chloride), poly( vinyl alcohol) and their blends with different components ratio has been investigated in accelerated laboratory conditions. It was found that PVC is less photostable than PVAL, in which the photocrosslinking is more efficient. The PVC/PVAL blends have higher photostability comparing to pure PVC but they were less photostable than PVAL alone.
