Abstract

FIELD: chemical technology. SUBSTANCE: method involves the use of extractant for washing off the finely ground reaction mass of polymer at increased temperatures and using vibrating. After washing off the reaction mass is used for synthesis of poly- and copolyethersulfones which were used as structural and insulating materials and diaphragms in industry and medicine. EFFECT: improved method of isolation and refining. 7 cl
