PROCESS FOR PRODUCING POLYMER FOAM, REACTION SYSTEM AND ISOCYANATE-REACTIVE COMPOSITION |
摘要 |
A process for preparing polymeric foams which comprises reacting : a) an organic polyisocyanate b) an isocyanate-reactive composition comprising : i) an organic polyfunctional isocyanate reactive composition comprising at least 50% w of polyfunctional isocyanate reactive compounds having a molecular weight of above 1500 wherein at least 25% of the isocyanate reactive groups are imino or enamino groups, and at most 50% by weight of polyfunctional isocyanate reactive compounds having a molecular weight of 60-1500, and ii) a catalytically effective amount of a carbodiimide promoting catalyst, and iii) optionally other catalysts and/or further conventional additives, in the substantial absence of water and chlorofluorocarbon blowing agent. r |
