PURPOSE: To produce the titled polyalkylene oxide of a narrow MW distribution, by polymerizing an alkylene oxide in the presence of a specified complex catalyst and an active hydrogen-containing compound and converting the terminal OH groups of the polymer into unsaturated groups. n CONSTITUTION: An organoaluminum compound (e.g., trimethylaluminum) is reacted with a porphyrin compound of formula I (wherein R 1 is H or a 4C or lower alkyl and R 2 is H or a 10C or lower hydrocarbon group) in a halohydrocarbon solvent to obtain a complex catalyst of formula II (wherein X is a halogen or R 1 ). An alkylene oxide is polymerized in the presence of said complex catalyst and an active hydrogen-containing compound (e.g., allyl alcohol) and the terminal OH groups of the obtained polymer are reacted with an alkali metal to convert them into alkoxide groups, which are then converted into unsaturated groups by reaction with an unsaturated active halogen compound having a terminal unsaturated group and an active halogen. n COPYRIGHT: (C)1986,JPO&Japio |
