Abstract: A process for polymerization of .alpha.-olefin comprises polymerizing an .alpha.-olefin in the presence of a catalyst containing the following catalyst components (A), (B) and (C): (A) a solid catalyst containing magnesium, titanium, a halogen element and an electron donor indispensably, (B) an organoaluminum compound, and (C) an orgnaosilicon compound represented by the following general formula: R12Si(OR2)2 (wherein R1 is an unsubstituted cyclic amino group, and R2 is a C1-24 hydrocarbon group). The process can produce an .alpha.-olefin polymer high in stereoregularity, melt flowability and melt flow rate. The process can also reduce a problem of the high pressure resistance to be ordinarily possessed by the reactor in bulk polymerization because of the hydrogen filled in a large amount.

Abstract: In the production of a conjugated diene polymer, if the yield gradually decreases, the yield can be recovered. A conjugated diene polymer is produced using a transition metal catalyst and an organic aluminum compound as a cocatalyst, but while a conjugated diene polymer is continuously produced, the yield gradually decreases. In response, the amount of cocatalyst that is supplied is adjusted based on the extent of production of deactivated material produced in the reaction system. More specifically, when the extent of production becomes a prescribed value or less, an increase in the amount of cocatalyst is started. Furthermore, when it is determined that the yield has sufficiently recovered, the increased amount of cocatalyst is stopped. In other words, the prescribed amount of cocatalyst prior to the increase is supplied.
