| titleOfInvention | Quaternary ammonium carboxylate intramolecular salt composition as a limited active catalyst for preparing polyurethane foams (FOAM) |
| abstract | The present invention relates to a method for producing a polyurethane foam, characterized in that the organic polyisocyanate is reacted with a polio under a catalyst composition containing a blowing agent, a pore stabilizer and a quaternary ammonium carboxylate intramolecular salt having the following general formula (I). It is about.n n n n n n n n Wherein R 1 -R 3 are each C 1 -C 12 alkyl, C 5 -C 8 cycloalkyl or heterocycle, C 6 -C 10 aral or heteroaromatic. In addition, R 1 and R 2 or R 1 -R 3 together with a nitrogen atom, piperidine, morpholine, triethylenediamine, imidazole, or 1,8-diazabicyclo- [5.4.0] undec It may be part of a nitrogen containing ring system such as -7-ene. R 4 is divalent R 1 . |
