Pulse radiolysis studies on radiation-induced polymerization reaction of α-methylstyrene

Pulse radiolysis studies on the polymerization reaction of α-methylstyrene was summarized. Pulse radiolysis with optical measurements as well as electric conductivity measurements showed that anionic radicals are very important intermediates in very dry system. These facts, together with the fact that the radiation-induced polymerization of α-methylstyrene is greatly accelerated by drying the monomer strongly indicate that the anionic radicals play a very important role in the polymerization.
