ABSTRACT:
A process for preparing a polyalkylene oxide having allyl end-group, by subjecting an alkylene oxide monomer to addition polymerization in the presence of potassium hydroxide in an amount of 2 to 30% by mole to the monomer at a temperature of 20.degree. to 100.degree.C., and reacting the polymerized alkylene oxide with an allyl halide compound, or by subjecting the monomer to addition polymerization in the presence of potassium hydroxide, reacting the polymerized alkylene oxide with an organic polyhalide and then reacting with an allyl halide compound. Potassium hydroxide is preferably employed in combination with the specific initiator. There can be prepared polyalkylene oxide of which all of the chain ends are substantially allyl group.
