Zusammenfassung:	Polyol composition (I), comprises a polyol component (II) and polyisocyanate (III) (preferably diisocyanate), where (I) is prepared by thereaction of (II) and (III) and the relationship of hydroxy groups of (II) to the isocyanates of (III) is more than 2:1. Independent claims are also included for: (1) an isocyanate prepolymer (Ia), obtained by reaction of (I) with polyisocyanate (IV); (2) a pressure container (V) comprising (Ia), a diluent and/or a liquid gas; and (3) a polyurethane-foam material (Ib) obtained by discharge from a (V) followed by reaction with air humidity.
