AMINE-MODIFIED POLYURETHANE (UREA) FOAMS AND A PROCESS FOR THEIR PRODUCTION ABSTRACT OF THE DISCLOSURE Amine-modified polyurethane (urea) foams are made by reacting a polyisocyanate with a relatively high molecular weight isocyanate-reactive compound in the presence of a difunctional and/or polyfunctional amine corresponding to the formulate) and/or Image in which X, R', R", m and n each represent specified groups or values. The amine is used in a quantity of from 0.01 to 5 parts by weight for every 100 parts by weight relatively high molecular weight isocyanate-reactive compound. Known additives and auxiliaries may also be included in the reaction mixture. The foams thus produced are characterized by improved mechanical properties and reduced amine odor. These foams are useful as cushioning materials, insulating materials, coatings and elastomeric materials.
