摘要：

Radiation-induced graft polymerization of styrene from the liquid phase on to poly(ethylene terephthalate) nuclear membranes and films has been investigated. Grafting was carried out by the methods of pre-irradiation in air and in vacuum. It is shown that dose rate does not affect the rate of graft polymerization. Linear dependence of the limiting grafting yield on dose has been obtained for pre-irradiation in vacuum. The influence of sample storage time after completion of the irradiation on graft polymerization kinetics has been studied: for pre-irradiation in vacuum, grafting yield passes through a maximum; for pre-irradiation in air, grafting yield decreases continuously and the rate of its decrease is greater for samples kept in air than in vacuum. © 1990.
