stabilizing agent the fire retardant etc may be added to either the prepolymer or remaining polyol or both prior to the mixing of the component whereby at the end of the reaction a rigid polyurethane foam is provided urethane elastomers and coatings may be prepared also by known techniques in accordance with the present invention wherein the catalyst of this invention is used the invention will be illustrated further with respect to the following specific examples which are given by way of illustration and not as limitations on the scope of this invention to a 1 liter flask equipped with a dean stark trap was place 245 5 grams of a mixture of n n n u2032 trimethylbis aminoethyl ether and n n n u2032 n u2032 tetramethylbis aminoethyl ether 81 5 tri 16 9 tetra and 1 6 di 160 grams of cyclohexanone and 81 grams of xylene the mixture was heated to reflux and the water removed by an azeotrope using the dean stark trap once all the water had been remove the flask was equipped with a 6 inch vigreux column and the reaction mixture distilled first at atmospheric pressure to a head temperature of 155 c then under 10 mm hg vacuum to a head temperature of 90 c to thereby remove the tetramethyl compound to a 500 ml flask equipped with an azeotroping head which returns the heavy layer water layer to the reaction flask and allows for the removal of the light organic layer was charged 120 4 grams of the bottoms from the previous reaction and 120 grams of water the mixture was heated to reflux removing the cyclohexanone by hydrolysis of the enamine by the azeotrope formed with water then remove the water to a distillation flask equipped with a.
