Abstract: Isocyanate-reactive compound with at least 90% sec. OH groups is prepared by reacting triols with propylene- or butylene-oxide. Isocyanate-reactive compound has a hydroxy number of 600-1000, 2.5-3.0 OH groups on average of which 90-100% are sec. groups, is prepared by reacting compounds with three OH groups with propylene oxide or butylene oxide. Independent claims are also included for a mixture of the above compound (i) and a polyester alcohol(s) (ii) with 20-50% sec. OH groups, an average functionality of 1.9-2.5 (2) and an OH number of 200-300 mg KOH/g, the preparation of polyisocyanate polyaddition products by reacting the above compounds or the above mixture with isocyanates in the presence of catalysts, propellants and additives and aids and the obtained polyisocyanate polyaddition products.
