ABSTRACT:
An improved process of preparing hydroxy-terminated aliphatic polyethers having pendant alkyl azide groups is disclosed. The process entails reacting metal azide and hydroxy-terminated aliphatic polyether having pendant haloalkyl groups at elevated temperatures. The improvement comprises using a liquid reaction medium that is relatively non-polar and comprises a polyalkyleneoxide having (a) a molecular weight above about 200 and (b) miscibility with the hydroxy-terminated aliphatic polyether having pendant haloalkyl groups at temperatures greater than about 80.degree. C.
