Abstract: Disclosed is a method for the preparation of FCHC-free polyurethane soft (molded) foam materials with low density, by reacting (A) liquid polyisocyanate mixtures containing bound urethane groups, containing 22 to 30 weight percent of NCO groups, which in turn are prepare by reacting a mixture of diphenylmethane-diisocyanate and polyphenyl-polymethylene-polyisocyanates (raw MDI) with at least one polyoxypropylene-polyoxyethylene-polyol with a functionality between 2.5 and 3.6, a hydroxyl number between 50 and 90 and a polymerized ethylene oxide group concentration ranging from more than 30 to less than 50 weight percent, relative to the weight of the polymerized ethylene oxide and 1,2 propylene oxide groups, or by reacting of 4,4' diphenylmethane-diisocyanate (MDI) or an MDI-isomeric mixture with the above-named polyoxypropylene-polyoxyethylene-polyol to form an NCO-group-containing quasi-prepolymer, and diluting this quasi-prepolymer with raw-MDI, with (B) higher-molecular polyhydroxyl compounds and, if appropriate, (C) low-molecular chain lengthening and/or cross-linkage promoting materials, in the presence of (D) propellants, (E) catalysts as well as, if appropriate, (F) auxiliary materials and/or additives.

Foamed materials are prepared by reaction of (a) isocyanates with (b) compounds reactive to isocyanates of molecular weight 500-8500 and optionally (c) chain lengthening and/or crosslinking agents of molecular weight 60-499 in the presence of (d) a propellant and (e) a catalyst, and optionally (f) adjuvants and/or additives. The isocyanate (a) is 2,4- and or 2,6-toluylenediisocyanate and/or 4,4, 2,2, and/or 2,4-diphenylmethane diisocyanate, and the reaction is carried out in the presence of (e1) 0.02-0.08 wt.% triethylenediamine and 0.05-0.3 wt.% of at least one aminoalkyl and/or aminophenyl-imidazole (e2) of formulas (I) and/or (II): where: R -R = phenyl, halogen, H, 1-10C linear or branched alkyl, 1-4C alkoxy, N-mono- or 1-4C N,N-dialkylamino, N-mono- or N,N-dialkylaminoalkylene, i.e. 1-4C alkyl and 2-4C alkylene, R = R , with the exception of halogen and alkoxy; Y = H, 2-4C hydroxalkyl, or hydroxypolyoxyalkyl with 2-20 alkylene oxide units, X (catalyst) = 2-6C alkylene or phenyl, Z = H, 1-4C alkylene, phenyl, 2-4C hydroxyalkyl, or 2-20C hydroxypolyoxyalkylene, and the weigh proportions of (e1) and (e2) are based on the weight proportion of component (b)(sic).
