Abstract

PURPOSE: To prepare a polyurethane foam useful for sheet cushion materials of automobile seats, etc., having a complicated form, a low density, and high elasticity, by cold molding a mixture of specific polyxyalkylene polyols.
CONSTITUTION: (A) A polyoxyalkylene glycol having an average molecular weight of 4,000W5,000 and terminal hydroxyl groups, 60W80% of which are primary hydroxyl groups, is prepared by addition reaction of an alkylene oxide (e.g. ethtlene oxide, etc.) with a trior multivalent polyhydric alcohol (e.g. glycerol, etc.). (B) A polyoxyalkylene glycol having an average molecular weight of 5,500W7,500 is prepared in the similar way. A mixed polyoxyalkylene polyol comprising 40W 80wt% of (A) and 60W20wt% of (B), is compounded with an organic polyisocyanate (e.g. tolylene diisocyanate, etc.), a catalyst, a blowing agent, a foam stabilizer, etc., thereafter foamed and cured preferably at ≤60°C to give the desired foam.
