INFLUENCE OF THE COMPOSITIONAL HETEROGENEITY ON THE STRUCTURE, PHASE STATE AND PROPERTIES OF CONCENTRATED-SOLUTIONS OF POLYCARBONATE POLYDIMETHYLSILOXANE BLOCK COPOLYMERS AND MEMBRANES ON THEIR BASIS

Structural changes of concentrated solutions of polyblock polycarbonate - polydimethylsiloxane copolymers of various compositional heterogeneity have been studied. An increase of heterogeneity is accompanied by the growth of supermolecular formations in solution and results in appearance of the micellar structures. The character of the structure and permeability of membranes depends not only on the phase state of solutions, but is related with compositional heterogeneity of block copolymers.
