The radiation-induced crosslinking of polyvinylidene fluoride (PVDF) was studied using N,N'-m-phenylenedimaleimide (PhDMI). It was shown that the addition of sensitizer results in a nearly two-fold decrease in the absorbed dose required for crosslinking. The main radiation-chemical parameters of the crosslinking process were determined. The mechanism of PVDF crosslinking in the presence of N-phenylmaleimide (PhMI), PhDMI and its saturated analogue, N,N'-m-phenylenedisuccinimide (PhDSI) was studied by ESR spectroscopy. The results indicate the probability of forming a crosslinked structure, which is really a system of interpenetrating networks. © 1991.
