Abstract
PURPOSE: To make it possible to omit an operation for removing catalyst residues from the formed polymer, by polymerizing ethylene in the presence of a catalyst containing a specified vanadium-containing solid catalyst and an organoaluminum compound.
CONSTITUTION: A Grignard compound of formula II, wherein R2 is a 1W8C alkyl and X1 is a halogen atom, is reacted with a reaction product between an aluminum halide and an organosilicon compound of formula I, wherein R1 is a 1W3C alkyl. Next, ethylene is polymerized in the presence of a solid catalyst component obtained by contacting the above-produced solid with a vanadium oxytrihalide and an organoaluminum compound of formula III, wherein R3 is a 2W6C alkyl and X is a halogen atom. As the compound of formula I, there is mentioned tetramethoxysilane or tetraethoxysilane. As the compound of formula II, there is mentioned methylmagnesium chloride or ethylmagnesium chloride.
