FIELD: polymerization processes and catalysts.
SUBSTANCE: alkylene oxide polymerization is conducted in presence of catalyst based on bimetallic cyanide complex and initiator containing hydroxyl group. Al last part of the catalyst is preliminarily subjected to treatment by ultrasonic and/or electromagnetic emission. Invention discloses both polymerization catalyst treatment method and catalyst itself.
EFFECT: enabled production of polyether-polyols with low unsaturation level and increased activity of catalyst.
