Abstract
Polgbutadiene-polystyrene diblock copolymer lamellar supercrystals developed by binary mixture of PS-PB block copolymers with different molecular weights have been studied by SANS on the diffractometer "Membrana-2". The dependence of the lattice spacing and the radii of gyration of PB chains on the molecular-weight parameters of a domain have been studied. It turned out that the conformation of PB chains is dependent on the concentration of surrounding short chains.
