アルミニウム化合物およびその製造方法、オレフィン重合体製造用触媒並びにオレフィン重合体の製造方法

Document Type and Number:

Japanese Patent JP4090100

Kind Code:

B2

Abstract:

A catalyst for olefinic polymer production comprises (a) a penta-coordinated, organic aluminium oxide compound, (b) an alkylating agent and (c) a compound of a transition metal of Group IV, V, VI or VIII of the Periodic Table. Olefins are homopolymerized or copolymerized in the presence of the catalyst for olefinic polymer production to produce olefinic polymers. The process does not require a promoter of methylaluminoxane, with which the problem is low solubility and low storage stability. Using therein the penta-coordinated, organic aluminium oxide compound which is relatively inexpensive and can be produced easily, the process realizes high-yield production of olefinic polymers.
