摘　　要：一般认为 ,受阻胺型光稳定剂不适用于PVC塑料中 ,本文则探索性地将其应用于耐候性要求比较高的PVC农用棚膜中 ,结果表明 ,受阻胺型光稳定剂的光稳定效果完全可以同目前PVC棚膜中应用的UV 5 31和UV 9相媲美 。Traditionally,hindered amine light stabilizers(HALS) are not suitable for Polyvinyl Chloride(PVC).In this study,HALS were experimentally used in PVC agricultural films,it was shown that photostabilization functions of HALS were similar to UV 531 and UV 9 which were applied in PVC agricultural films,and the films showed better results of photostabilization when combined with them.
