FIELD: organic chemistry, polymer materials.
SUBSTANCE: polyester-polyols are obtained by double metalcyanide catalyzed polyaddition of alkylenoxide to starting material containing active hydrogen atoms. Alkylenoxide is continuously fed into reactor during induction period while maintaining constant pressure in reactor.
EFFECT: method for polyester-polyol production with decreased induction time.
