PROCESS FOR POLYMERIZING OLEFIN

摘要

In a process for polymerizing an olefin in the presence of a catalyst system combining an organoaluminum compound with a hydrocarbon insoluble solid catalytic component prepared by treating a hydrocarbon solution containing a magnesium compound, and a titanium compound with an aluminum halide having the formula (R1 represents an alkyl, aryl or cycloalkyl group and X1 represents a halogen atom, and ? is 1 ? ? ? 2), the improvement in which the magnesium compound is a compound having the formula (R2 represents an alkyl, aryl or cycloalkyl group; X2 represents a halogen atom; and m is 1 or 2) and the titanium compound is a compound having the formula (R3 represents an alkyl, aryl or cycloalkyl g.oup; X3 represents a halogen atom; n is 1, 2 or 3).
