FIELD: chemistry.
SUBSTANCE: method involves preparation of a reaction mixture containing at least one polyisocyanate, unsubstituted or inertly substituted alkyl ester of a fatty acid, having on average at least 0.8 hydroxymethyl groups per molecule and at least one polyol or polyamine compound, a catalyst and a foaming agent, and hardening the reaction mixture to form foamed polyurethane. The ester is an ester of a hydroxymethyl-containing fatty acid, having 12-26 carbon atoms and selected from esters having structures A1, A2, A3 of formulae 
and 
respectively.
EFFECT: obtaining foamed polyurethane having good physical and mechanical characteristics.
