ABSTRACT:
Polypropylene oxide having unsaturated end groups is prepared by polymerizing alkylene oxide in the presence of a complex catalyst prepared by reacting an organoaluminum compound with a porphyrin compound and an active hydrogen-containing compound and converting at least one hydroxyl end groups into an unsaturated end group(s), the prepared polymer having a narrow distribution of molecular weight.
