Abstract: Polyisocyanates for the production of flexible polyurethane foam comprise prepolymers with NCO content = not more than 17.5 wt%, obtained by reacting 4,4'-MDI with polyether-alcohol(s) (with 10-20 wt% ethylene oxide units) to give a prepolymer with NCO content = 10-14 wt% and then reacting this with polyphenylene-polymethylene-polyisocyanates. A method for the production of flexible polyurethane foam with a density of 30-80 g/l by reacting (a) polyisocyanates with (b) compounds with at least 2 isocyanate-reactive hydrogen atoms in presence of (c) blowing agents. Component (a) comprises polyisocyanate prepolymers with an NCO content of not more than 17.5 wt%, obtained by (i) reacting 4,4'-MDI with polyether-alcohol(s) showing an OH number of 20-60 mg KOH/g and containing 10-20 wt% ethylene oxide units in the polyether chain (based on total alkylene oxide content), to give a prepolymer with an NCO content of 10-40 wt% and then (ii) mixing the prepolymer with polyphenylene-polymethylene-polyisocyanates. An independent claim is also included for flexible polyurethane foam with a density of 30-80 g/l obtained by this method.
