Effect of electron scavengers on the formation of paramagnetic species upon radiolysis of polystyrene and its low-molecular-weight analogs

摘要: The effect of electron scavengers on the composition and yields paramagnetic species upon radiolysis polystyrene was examined. Various mechanisms reactions radical cations (holes) in low-molecular-weight aromatic hydrocarbons are discussed. dimeric were found to be trapped benzene irradiated presence at 77 K. yield shown increase markedly small amounts (<1%) chloroform benzyl chloride. results obtained show that ionic processes make a large contribution formation species. It is concluded radiation resistance due not only its chemical structure, but association phenyl rings solid polymer.
