摘要

Initiation mechanism of the photopolymerization of acrylonitrile and methyl methacrylate

usingbinary condensed aromatic hydrocarbon (CAH)-aniline systems as initiator

was studied. The strongerthe electron-donating ability of the aniline derivatives

the faster the the of photopolymerizationwill be. The radical intermediates produced by photoreaction between anthracene and anilinewere detected with ESR spectra. The initiation scheme involves the formation of exciplex betweenthe excited singlet state of CAH and the ground state of aniline as the first step

and then followed by proton transfer

leading to the generation of two kinds of radicals.From the end-group analysis of the polymers obtained

it is suggested that both kinds of radicals are involved in the initiation.
