CATALYST FOR OLEFIN POLYMERIZATION AND PROCESSES FOR ITS PRODUCTION |
摘要 |
The solid catalyst of this invention for olefin polymerization comprises a compound of a transition metal of Group IV of the periodic table and an aluminoxane as catalyst ingredients. The catalyst is characteristic in that it has a high specific surface area, and shows very high polymerization activity on the homopolymerization or copolymerization of olefins. Polymers obtained by using the catalyst of the invention have a high bulk density, a uniform particle size, a low fine powder content and a narrow molecular weight distribution, and in the case of copolymers, a narrow composition distribution as well.
