Abstract: 1. A process for preparing an elastic, compact or cellular polyurethane by reacting a) an organic polyisocyanate with b) an organic polyhydroxy compound in the presence of c) a catalyst and optionally d) a chain extending or crosslinking agent, e) a blowing agent, f) an assistand and/or an additive, wherein polyhydroxy compound b) comprises to an extent not less than 30% by weight, based on total component b), a di-, tri- or tetrafunctional polyether polyester polyol having a hydroxyl number of from 10 to 200 and having been prepared by esterification of i) a di-, tri- or tetrafunctional polyetherol having a hydroxyl number of from 15 to 250 with a carboxylic anhydride in the presence of N-methylimidazole and/or triethylenediamine as a catalyst to give a carboxylic monoester and subsequent ii) alkoxylation of the carboxylic monoester with an alkylene oxide in the presence of a mixture of N-methylimidazole and/or triethylenediamine and triphenylphosphine and/or a thiodialkylene glycol as a catalyst, the amount of catalyst being from 0.05 to 2.0 parts by weight, based on 100 parts by weight of the mixture of polyol and carboxylic anhydride or on 100 parts by weight of carboxylic monoester.

Abstract: Asymmetric polyether-polyols having a functionality of from 3 to 8, a hydroxyl number of from 15 to 112 and preferably a compatibility index of less than 50 DEG C are obtained by reacting a) one mol of a polyoxyalkylene glycol having a hydroxyl number of from 15 to 200 with b) from 0.1 to 2 mol of an epoxyalcohol of the formula in which R and R are identical or different and are a hydrogen atom or a -CH2OH radical, x is an integer from 0 to 9 and y is 0 or 1, preferably glycidol, and subsequent c) alkoxylation of the resultant trifunctional to octafunctional intermediate c) in the presence of basic catalysts until the hydroxyl number mentioned has been reached. The asymmetric polyether-polyols are particularly suitable for the production of open-cell polyurethane foams.
