Sensitization of radiation-chemical crosslinking of polyvinylidene fluoride by N,N′-m-phenylene dimaleimide

Abstract The authors have studied the sensitizing action of N,N′- m -phenylene dimaleimide on the process of radiation-chemical crosslinking of PVDF. The sensitizing action of N,N′- m -phenylene dimaleimide may be explained by the interaction of the vinylene groups of the diimide with PVDF with formation of transverse bonds. In presence of N,N′- m -phenylene dimaleimide the ratio of the radiation-chemical yields of degradation and crosslinking falls as result of rise in the radiation-chemical yield of crosslinking.
