Abstract
Conditions of preparation of ionogenic membranes based on the radiation induced polymerization of styrene on low-density polyethylene films (LDPE) were investigated. After optimization of the preparation conditions (radiation dose, concentration of the monomer solution, temperature of grafting), a series of samples with various degrees of grafting were prepared. Their sulfonation yielded cation-active membranes which were characterized by ion-exchange capacity, concentration membrane potentials, specific and area resistance, transport number of preferred ions, and permselectivity.
