摘要: Process for preparing a flexible foam by reacting a prepolymer having an NCO value of 3-15% by weight, which is the reaction product obtained by reacting an excessive amount of a polyisocyanate with a polyether polyol or a mixture of such polyols, said polyol or mixture having an average nominal hydroxyl functionality of from 2 to 6, an average hydroxyl equivalent weight of from 500 to 5000 and an oxyethylene content of at least 50% by weight, with water, the amount of water being 15-500 parts by weight per 100 parts by weight of prepolymer, at the start of the reaction the temperature of the prepolymer being 10.degree.-50.degree. C. and the temperature of the water being 10.degree.-50.degree. C. higher than the temperature of the prepolymer and a process for preparing a flexible foam by reacting the above prepolymer with water in the presence of a superabsorbent polymer.
