FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing polyether ester polyols which are used in producing polyurethanes. The method involves reacting initiating compounds with alkylene oxides with basic catalysis in the presence of fatty acid esters. The initiating compounds are compounds having Tserevitinov-active hydrogen atoms, and the fatty acid esters used are esters in which fatty acid radicals do not contain free OH groups.
EFFECT: method enables to obtain polyols which are based on reclaimable material and are used in polyurethane compositions as a component which is capable of reacting with isocyanates.
