FIELD: polyether polyols.
SUBSTANCE: polyether polyols contain 40-95 % of primary hydroxyl groups and >25 % in total of poly(oxyethylene/oxypropylene)-terminated oxyethylene blocks, obtained in presence of zeolite catalyst. Invention also relates to method for polyol production.
EFFECT: long-chain polyether polyols with high content of primary hydroxyl groups; decreased catalyst content.
