Abstract
PURPOSE: To obtain a polyethylene having a narrow range of MW distribution, by the polymerization of ethylene in an aliphatic or alicyclic hydrocarbon diluent containing an aromatic hydrocarbon, by use of a catalyst containing a Ti compound a V compound and an organic Al compound.
CONSTITUTION: Two kinds of catalyst consisting of (A) a solid material which is a mixture or a eutectic of a Ti compound (e.g., titanium tetrachloride) with a V compound (e.g., vanadium oxyalcoholate), insoluble in a hydrocarbon diluent, and of (B) an organic Al compound (e.g., triethylaluminum), are prepared. Then, in the polymerization of ethylene in an aliphatic or alicyclic hydrocarbon diluent (e.g., hexane or cyclopentane) by use of the catalyst system, the purpose polyethylene, excellent in impact strength and having a narrow range of MW distribution, is obtained in the presence of 0.05W20wt%, based on the diluent, aromatic hydrocarbon (e.g., toluene or styrene).
