Procedure
To a one-liter 3-necked flask equipped with a thermometer, stirrer, dropping funnel and a nitrogen inlet was 122 g (0.5M) of TMXDI (from American Cyanamid). Then 193 g (1.0 mole) of tetraethylene glycol monoamine was added over a 50 minute period keeping the temperature below 36° C. A clear viscous product was obtained.
