Abstract

PURPOSE: Titled inexpensive composition from which the polyol does not separate by homopolymerization of a monomer, prepared by reacting a poly(oxyalkylene) polyol or a low-MW polyol with both urea and an amine compound.
CONSTITUTION: A polyol composition for polyurethane synthesis is prepared by heating (A) a poly(oxyalkylene) polyol, e.g., an adduct between an alkylene oxide and a polyhydric alcohol such as ethylene glycol together with (B) urea and (C) an amine compound, e.g., 4,4'-diaminodiphenylmethane, at 70°C or higher under reduced pressure. In the production of foams, the use of this composition makes it possible to decrease the density of an extent larger than usual without affecting other properties and to produce thereby foams at low cost.
