Abstract: Prodn. of polyurethane foam involves reacting (a) organic and/or modified organic polyisocyanate(s) with (b) polyol(s) of relatively high mol. wt., which contain at least 2 reactive H atoms and (c) opt. low mol. chain extender and/or crosslinker in the presence of (d) blowing agent, (e) catalyst and (f) opt. additives. The novelty is that the catalyst comprises aminoalkyl- or aminophenyl-imidazole cpds. of formula (IA) and/or (IB). In (IA) and (IB), R ,R , R = 1-10C alkyl, 1-4C alkoxy, N-mono- and N,N-di-(1-4C)-alkylamino, N-mono- and N,N-di-(1-4C)-alkylamino-(2-4C)-alkylene, Ph, halogen or H; R = as R except halogen and alkoxy; X = 2-6C alkylene or phenylene; Y = H, 2-4C hydroxyalkyl or hydroxypoly-(2-20C)-oxyalkylene; Z = 1-4C alkyl, Ph or as Y. Also claimed is the use of (IA) and/or (IB), esp. 1-(3-aminopropyl)-imidazole (IC), 1-(3-aminopropyl)-2-methylimidazole (ID) or 1-(3-aminopropyl)-2-ethyl-4-methylimidazole (IE) as catalyst for the prodn. of polyisocyanate polyadducts.

Abstract: The invention relates to a process for the preparation of CFC-free flexible polyurethane(moulded) foams by reacting A) liquid polyisocyanate mixtures containing bonded urethane groups and containing from 20 to 30% by weight of NCO groups, themselves prepared by reacting a mixture of diphenylmethane diisocyanates and polyphenyl polymethylene polyisocyanates (crude MDI) with a polyether-polyol mixture having a hydroxyl number of from 120 to 25 comprising at least one polyoxypropylene glycol and at least one trifunctional polyoxypropylene polyoxyethylene polyol containing from 90 to 10% by weight of ethylene oxide units or by reacting 4,4'-diphenylmethane diisocyanate (MDI) or an MDI isomer mixture with said polyether polyol mixture to give an NCO-containing quasi-prepolymer, and diluting this quasi-prepolymer with crude MDI, with B) relatively high-molecular-weight polyhydroxyl compounds and optionally C) low-molecular-weight chain extenders and/or crosslinking agents, in the presence of D) blowing agents E) catalysts and optionally F) auxiliaries and/or additives, and to the urethane group-modified polyisocyanate mixtures (A) which can be used according to the invention.
