Analysis of radiation-induced structural changes in deuterated polybutadiene revealed that saturation, unsaturation, and double bond shifts occur. The closeness of the G(H2, HD, D2) to the G(H2) for conventional cis-polyisoprene indicated that the methyl group plays a minor role in the radiolysis of polyisoprene. Special monomers of Phase I, having the aromatic protective group attached to the structural repeating unit, were synthesized. Homopolymers and several additional copolymers of Phase I were synthesized. Three condensation polymers of Phase II, having the protective aromatic group in the main chain, were prepared. Compression set during irradiation continued to be an effective index of the radiation resistance of vulcanized rubber compounds. In general, rubber compounds without antirads required radiation exposures from 1.0 x 10 to the 8th power to 2.7 x 10 to the 9th power ergs/gram (C) to effect 50% net compression set. When antirads are present, the range becomes 3.0 x 10 to the 8th power to 4.4 x 10 to the 9th power.
