Abstract: The present invention relates to a process for preparing autocatalytic polyether alcohols by reacting H-functional starter substances containing at least one amino group which is catalytically active in the urethane reaction, in particular a tertiary amino group, and at least one group which is reactive toward alkylene oxides, in particular a primary and/or secondary amino group and/or hydroxyl group, with alkylene oxides, which comprises a) dissolving the starter substance in a solvent, b) reacting the solution with alkylene oxides.

Abstract: Deactivation of amine catalysts in polyisocyanate polyaddition products (PIPAP) after their preparation in order to avoid the formation of primary amines, especially primary aromatic amines, by means of additives which decrease the content of these amines, especially in soft polyurethane foams, i.e. by addition of groups I, II, and or VIII subgroups, is new.

Abstract: The present invention relates to a process for producing a polyurethane elastomer fiber, which comprises a) reacting polymeric diol with a substance reactive therewith to form an OH-terminated prepolymer, b) reacting the OH-terminated prepolymer with a diisocyanate to form an isocyanate-terminated prepolymer, c) reacting the isocyanate-terminated prepolymer with a chain extender, if appropriate a chain-terminating agent and if appropriate further additives to form the polyurethane elastomer, and d) spinning the polyurethane elastomer to form a fiber, in which there are less than 15% by weight of further polyurethane elastomers in the fiber. The present invention further relates to a polyurethane elastomer fiber obtainable by such a process, to its use for producing textiles, for example wovens or knits, and also to the use of a polyurethane elastomer for producing such a fiber.

Abstract: Reducing formaldehyde emissions from polyurethane foams comprises adding an amino-functional polymer before, during or after producing the foam. Independent claims are also included for: (1) polyurethane foam containing 0.0001 to less than 0.1 wt.% of an amino-functional polymer with a molecular weight (MW) of at least 500 and an amino functionality (AF) of at least 3, the MW/AF ratio being 40-500; (2) equipment articles comprising the polyurethane foam; (3) use of amino-functional polymers to improve the mechanical properties of polyurethane foams.
