Abstract: Preparation of viscoelastic polyurethane (PU) - soft integral foam materials (I) comprises: reaction of polyisocyanate (A) with compounds (B) of at least two isocyanate group reactive hydrogen in the presence of propellants (C), where (A) is diphenylmethanediisocyanate and/or its conversion products and/or mixtures from (A) of polymethylene polyphenyl polyisocyanate and (C) is at least a physical propellant. An independent claim is also included for (I), prepared by the method.

Abstract: Carbamate solutions obtained by reacting carbon dioxide with aminoalkyl-alkanolamines containing one or two terminal hydroxyl groups in hydroxyl group-containing organic solvents. Carbamate solutions, obtained by reacting alkanolamine(s) with carbon dioxide in hydroxyl group-containing organic solvent(s) with a mol. wt. of 60-600, in which the carbamate contains at least 0.51 mol bound CO2 per mol alkanolamine and the alkanolamine has the formula (I), (II) or (III) H2N-X-OH (I) HO-X-Y-OH (II) HO-X-NR -(CR R )n5-OH (III) X = -((CR R )n1NR )n2-((CR R )n3NR )n4-(CR )n5-; Y = -(NR -(CR R )n3)n4-(NR -(CR R )n1)n2-; n1, n3, n5 = 1, 2, 3 or 4; n2, n4 = 0, 1, 2, 3, 4, 5 or 6; (n2 + n4) = 1 or more; R -R = H or 1-20C aliphatic, cycloaliphatic, araliphatic or aromatic groups Independent claims are also included for processes for the production of foam, flexible foam and flexible or semi-rigid integral foam based on polyisocyanate-polyaddition products, with the aid of these carbamate solutions as blowing agents.
