| titleOfInvention |
The use of n-(aminoalkyl) pyrrolidines as catalysts for the polyisocyanate polyaddition process |
| abstract |
The present invention relates to a process for preparing polyisocyanate polyaddition products by reacting (a) polyisocyanates with (b) relatively high molecular weight compounds containing at least two isocyanate-reactive hydrogen atoms and (c) chain-extending agents, in the presence of (d) N-(aminoalkyl)pyrrolidine catalysts corresponding to formula (I) (see Formula I) in which R is a C2-12 alkylene group (optionally containing 0 or N atoms but not isocyanate-reactive groups) and R' is hydrogen or a C1-4 alkyl group, (e) optionally, other known catalysts, and (f) other known additives. |
