Phase state, structure and rheological properties of concentrated solutions of the polyblock copolymer of polyarylene sulphone oxide and polybutadiene in selective solvents

Abstract

The link between tke phase state, structure and rheological properties of concentrated solutions of the polyblock copolymer of a polyarylene sulphore oxide and polybutadiene with increase in the selectivity of the solvent has been studied. The phase diagram of the system block copolymer-solvent-selective precipitant has been obtained. The specifics of the equilibrium swelling of the block copolymers in mixtures of good and selective solvents determined by the partial destruction of the domains has been established.
