Abstract: A graft macromer, comprising the reaction product of at least one macromer being at least one molecule which comprises in its structure one or more hydroxyl-terminated polyether and/or polyester chains, with at least one grafting compound which comprises in its structure at least one at least monoalkoxylated or at least monohalogenated silyl group and at least one alkyl, cycloalkyl or aryl containing group which is reactive towards the hydroxyl group of the macromer, is used for dispersing e.g. SiO2 in a polyol.

Abstract: Disclosed herein is a process for producing polyurethanes including mixing (a) aromatic polyisocyanate with (b) polymeric compounds having isocyanate-reactive groups, (c) optionally chain extender and/or crosslinking agent, (d) catalyst, (e) 0.1% to 5% by weight, based on the total weight of the components (a) to (f), of at least one cyclic urea structure of general formula 1




where —X— represents a substituted or unsubstituted, 3-membered radical and R represents a radical (f) optionally blowing agent and (g) optionally additives to afford a reaction mixture and reacting the reaction mixture to afford the polyurethane. Further disclosed herein are a polyurethane obtainable by such a process and a method of using such a polyurethane foam for producing cushions, seat pads and mattresses.
