Abstract
PURPOSE: To easily adjust the MW of a polymer obtained, by the polymerization of an olefin in an aliphatic or alicyclic hydrocarbon diluent containing a monocyclic aromatic hydrocarbon, by use of a catalyst consisting of chromium oxide and an organic Al compound.
CONSTITUTION: In the polymerization of an olefin (e.g., ethylene or propylene) in an aliphatic or alicyclic hydrocarbon diluent (e.g., hexane or cyclopentane) by use of a catalyst system consisting of chromium oxide and an organic Al compound (e.g., trimethylaluminum or triethylaluminum) supported on silica, alumina or silica-alumina, the polymerization is carried out in the presence of 0.05W10wt%, based on the diluent, monocyclic aromatic hydrocarbon (e.g., toluene or styrene) as an MW adjustor. Thus it is possible to adjust average MW of the polymer prepared to such an extent as to easily mold the polymer.
