Radiation Induced Radical Reactions in Poly(Chloroalkyl Methacrylate)s--Triallylisocyanurate Mixtures

Radical generation after gamma -irradiation at 77K and radical reactions during temperature increase are discussed for the polymers poly(2-chloroethyl methacrylate) and poly(1,2,2,2-tetrachloroethyl methacrylate), mixed with triallylisocyanurate (TAIC). After the radiation interaction radicals were generated in the ester alkyl side groups of the polymer by chlorine abstraction in both polymer--TAIC mixtures. Radical transfer to TAIC occurred during temperature increase to produce allyl radicals. Hence, the high radiation sensitivity of Cl-containing polymers was combined with the reactivity of allyl radicals of TAIC in such polymer--TAIC mixtures. 17 ref.--AA
