Abstract: The invention relates to a process for preparing prepolymers containing isocyanate groups by reacting a) diisocyanates with b) compounds having at least two hydrogen atoms which are reactive toward isocyanate groups in the presence of c) catalysts, and subsequently separating off the excess monomeric diisocyanates, wherein the diisocyanates a) used are unsymmetrical diisocyanates and the catalysts c) used are organometallic catalysts and these organometallic catalysts are removed, blocked or deactivated before the monomeric diisocyanates are separated off.

Abstract: The invention relates to a method for producing polyurethanes by reacting an isocyanate constituent (B) with a polyol constituent (A). The inventive method is characterized in that ethylene glycol (C1) and diethylene glycol (C2) are added as chain-lengthening agents to the reaction. The invention also relates to the use of the polyurethanes for producing shaped bodies, particularly shoe soles.

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.
