    Abstract: According to the inventive method, the polyurethane foams are produced by reacting isocyanates with compounds that react with isocyanates in the presence of foaming agents and optionally, catalysts, additives and/or auxiliary agents. The method is characterised in that the reaction is carried out in the presence of at least one of the following compounds (i): alpha , beta -unsaturated carboxylic acid, alpha , beta -unsaturated carboxylic acid derivative, alpha , beta -unsaturated ketone and or alpha , beta -unsaturated aldehyde.

    Abstract: A polyisocyanate-polyaddition product is prepared by reaction of isocyanates (i) with compounds reactive to isocyanates in the presence of catalysts, propellants, additives and/or adjuvants, and (ii) at least one acid and/or at least one non-anhydride acid derivative. Independent claims are included for: (1) A mixture containing (i) at least one isocyanate and (ii) at least one acid and/or non-anhydride acid derivative, in which (ii) is present in amount 0.01-20 wt.% on the wt. of mixture, and the acid groups or derivative groups of (ii) are present in molar excess to the amines optionally present in the mixture; (2) A polyisocyanate-polyaddition product obtainable as above.
