PURPOSE:To obtain a raw material able to be molded at high speed with excellent processability by adding 3,5-diethyltoluene-2,4-diamine, etc., to a raw material for polyurethane foam containing polyether polyol as principal component. CONSTITUTION:100 pts.wt. polyether polyol as a raw material for polyurethane foam containing polyether polyol as principal component is mixed with preferably 0.1-1.0 pt.wt. 3,5-diethyltoluene-2,4-diamine, 0.1-1.0 pt.wt. 3,5- diethyltoluene-2,6-diamine, preferably 1.0-10 pts.wt. polytetramethylene oxide-di-p- aminobenzoate, preferably 0.1-5.0 pts.wt. alkylbis(4-aminobenzoate), preferably 0.1-5.0 pts.wt. polyoxyalkylenediamine and preferably 0.1-5.0 pts.wt. polyoxyalkylenetriamine to afford a raw material suitable for one-shot method at a low temperature. |
