Role of chain chemical heterogeneity in radiation chemistry of polyethylene

Effect of anomalous chains of different chemical nature on laws of radiation-chemical transformations in polyethylene (PE) and on properties after γ-radiation is shown using ethylene copolymer with styrene, methyl methacrylate, silicon-, phosphorus-, tin-, iron-containing copolymers. It is established that general transmission of absorbed energy and a charge goes to the PE chains of the anomalous structure being present in the chain. The place of radiation-chemical reaction proceeding is determined by the abovementioned fact. The supposition that chain chemical heterogeneity of real polymers is the reason of radiolysis deviation at the initial stage of irradiation from static laws is given
