Abstract: 1. A process for the manufacture of dimensionally stable polyurethane foams by releasing, and curing by interaction with the atmosphere preferably with atmospheric moisture, a storage-stable mixture, which contains blowing agents and is under pressure, of prepolymers which contain isocyanate groups and are based on polyols and organic polyisocyanates, wherein the polyols used are difunctional to octafunctional polyester-polyols and/or polyether-polyols which have a hydroxyl number of from 40 to 500 and contain chemically bonded tertiary amino groups in the polymer chain, or mixtures of such polyester-polyols and/or polyeter-polyols, containing tertiary amino groups, with nitrogen-free polyester-polyols and/or polyether-polyols.

Abstract: O.Z. 0050/032961 of the disclosure: A process for the manufacture of dimensionally stable polyurethane foams by releasing, and curing by interaction with the atmosphere, a mixture, which is under pressure, of prepolymers, containing isocyanate groups, and blowing agents, with or without assistants and additives, wherein the prepolymers, containing isocyanate groups, are obtained by reaction of organic polyisocyanates with difunctional to octafunctional polyester-polyols and/or. polyether-polyols, containing chemically bonded tertiary amino groups in the polymer chain, or, preferably, with mixtures of such polyester-polyols and/or polyether-polyols and nitrogen-free polyester-polyols and/or polyether-polyols.
