FIELD: polymer production. SUBSTANCE: polyurethane and polyurethane foams are prepared by interaction of polyisocyanates with oily or fatty component and, if necessary, in presence of blowing agent, catalyst, and at least one directional additive. Method is distinguished by said oily and fatty component is product of reaction of amines and, if necessary, water with oils and fats non-functional with respect to isocyanates. EFFECT: simplified process. 9 cl, 12 ex
