A process for producing an unsaturated group-terminated high-molecular weight polyalkylene oxide by adding an alkali metal and/or an alkali metal compound capable of producing an alkali metal hydroxide on reaction with water to a hydroxyl-terminated polyalkylene oxide having a repeating unit represented by formula -R¹-O- (wherein R¹ represents a divalent alkylene group having from 2 to 8 carbon atoms) to substitute the hydrogen atom of the hydroxyl end group with an alkali metal (alkoxidation) the resulting polyalkylene oxide is reacted with a polyhalogen compound to increase the molecular weight of the polyalkylene oxide and then additional alkali metal and/or alkali metal compound is added before reacting the resulting high-molecular weight polyalkylene oxide with an unsaturated halogen compound to introduce an unsaturated group to the molecular chain terminals. The first addition of alkali metal and/or alkali metal compound capable of producing an alkali metal hydroxide on reacting with water is added in an amount equivalent to or less than the hydroxyl end groups of said polyalkylene oxide and second addition of alkali metal and/or alkali metal compound is added in an amount equivalent to or greater than the remaining hydroxyl end groups.
