Conductivity of styrene-butadiene block copolymers upon stationary irradiation with fast electrons

Tie dependences of radiation current density in polystyrene (PS), polybutadiene (PB) and block-copolymers of butadiene with styrene of various content are studied under variation of electric field intensity and dose rate. In a number of block-copolymers significant deviation of values of radiation conductivity constant and dispersion parameter from expected at additive contribution in radiation ones electric conductivity of both components are detected. A conclusion is made on transfer current carriers of generated during the process of irradiation from PS to PB microdomains. 21 refs., 6 figs
