摘要
本文研究了通过改变复合光敏剂体系中光敏剂Ａ、光稳定剂Ｂ的配比Ｒ＝Ｃ＿Ａ／Ｃ＿Ｂ（摩尔比），来考察薄膜的诱导期、脆化时间的变化，以及碳基指数、拉伸强度随辐照时间的变化。结果表明，添加此复合光敏剂体系的薄膜的诱导期随Ｒ的增大（即光稳定剂用量减少）而减少，脆化时间也随Ｒ的增大而减少。
Composite photo-sensitier system contains sensitizer A and antioxidant B. With thechange of the ratio=C_A/C_B(in mol),induction period. embrittlement time of PE film,thecurve of carbonyl index and tensile strength to irradiation time were studied, The results showthat induction period decreases obviously with the increasing of the ratio,embrittlemen time decreases likewise.
