Abstract
Official abstract text for this publication.
The present invention relates to the use of nitrogenous compounds of formula (I) and/or corresponding quaternized and/or protonated compounds for production of polyurethanes, to compositions comprising said compounds and also to polyurethane systems, in particular polyurethane foams, obtained using said compounds.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for making a polyisocyanate polyaddition product comprising mixing (1) from 20 wt % to 95% wt %, the wt % based on the weight of the polyisocyanate polyaddition product, of a nitrogenous compound and/or corresponding quaternized and/or protonated compound and a polyol component with an isocyanate component and a blowing agent and reacting this composition, wherein this nitrogenous compound conforms to formula (III) wherein the compound of formula (III) by Williamson's ether is synthesised by reacting 2-chloro-methyl ether with an excess of at least two equivalents of pyrrolidine and; (2) from 0.1 wt % to <30 wt % based on the weight of the polyisocyanate polyaddition product of ingredients including, a) 1-(2-hydroxyethyl)pyrrolidine, b) 2-(2-(pyrrolidin-1-yl)ethoxy)ethanol, and c) 1-(2-(pyrrolidin-1-yl)propoxy)propan-2-ol. 2. The process according to claim 1 , further comprising at least one solvent, wherein the mass ratio of total catalyst of formulae (III) to solvent is in the range from 100:1 to 1:4.
