摘要

本文以硅橡胶膜为基材研究了与N-2-乙烯基吡咯烷酮（N-VP）或4-乙烯基吡啶（4-VP）共辐射接枝中的酸效应。结果表明，甲醇-N-VP与硅橡胶共辐射接枝体系中，在较大的剂量范围内酸对接枝反应有抑制作用。但酸对甲醇-4-VP体系的接枝反应却依然起敏化作用。虽然体系中酸度有上述影响，但剂量率、单体浓度的变化并不影响酸抑制或敏化接枝反应的总趋势。文中也讨论了上述接枝反应中酸效应的机理。

Abstract

In present work, the acid effect in radiation-induced grafting of N-vinyl-pyrrolidone N-VP or 4-vinyl pyridine (4-VP) onto silicone rubber was investigated. It was found that in methanol-N-VP systems the radiation grafting yields were inhibited by adding of acid (H,2,SO,4, 1×10,-2,mol/L) during a large regions of dose. On the opposite, acid enhanced the radiation grafting yields of 4-VP. Dose rate and concentraction of monomers did not change the tendence of results obtained. Mechanisms of acid effects in both systems were discussed.
