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.
