MECHANISM OF RADIATION-CHEMICAL PROCESSES IN POLYCARBONATE-POLYALKYL TEREPHTALATE SYSTEMS AND THEIR COMPONENTS

The work covers the mixtures of the polycarbonate and polyalkyl terephthalates, their components and diethyl terephthalate. The aim is to obtain the experimental data about composition and localization of the radiolysis products of the polycarbonates, polyalkyl terephtalates and mixtures on their base, to study the influence of the phase and chemical composition of the polycarbonate-polyalkyl terephthalate mixtures on the mechanism of the radiation-chemical processes in them. The formation of the dia- and paramagnetic particles in the polymer mixing systems with different chemical and phase structure by the spectroscopic methods has been firstly investigated systematically. The high sensitivity of the EPR signals in the radical pairs forming from polycarbonate component has been demonstrated. The data about formation of the cyclohexadienyl type radicals at radiolysis have been obtained for terephthalates.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
