Abstract

PURPOSE: To prevent post polymerization and thereby to obtain a polyolefin showing improved polymer recoverability, by polymerizing an olefin in the presence of a Ziegler-Natta catalyst, adding a branched chain alcohol and separating the unreacted olefin.
CONSTITUTION: In the production of polyolefin comprising the steps of: polymerizing an olefin in the presence of a catalyst containing a transition metal compound and an organometallic compound, i.e., Ziegler-Natta catalyst, and separating the unreacted olefin from the reaction mixture containing the catalyst, a 3W8C branched chain alcohol is added in the step of separation. The amount of the alcohol added is 0.5W10mol per mol transition metal compound of the polymerization catalyst. By specifying the amount of the alcohol added within the above range, the catalyst contained in the reaction mixture is deactivated and stabilized. The reason for this is perhaps that a stable complex is formed between the added alcohol and the transition metal compound.
