Study of the structure and transport properties of block copolymers of styrene with butadiene points out the essential increase of the electron-hole conductivity in the PS-microdomain for the case of its two-layer structure especially when the PS homopolymer spheroids are localized near the sublamelar boundary. The less dense packing of star-like chains of the block copolymer comparing with the linear ones results in the lesser efficiency of the charge transfer. Features of the microstructure of the PS-microdomain are shown to affect the concentration of dimers - paired associates of phenyl rings. The dimer is assumed to play the role of the intermolecular bridge in the charge transfer resulting in the percolation dependence of the radiation-induced electrical conductivity on the content of dimers.
