SOLID CATALYST FOR OLEFIN POLYMERIZATION AND PROCESS FOR ITS PREPARATION

摘要

The catalyst comprises a compound of a transition metal of the group IV of the periodic table, aluminoxane, and fine particles of an organic or inorganic carrier. This catalyst shows a significantly large polymerization activity on polymerization and copolymerization of olefin, and can give a polymer or copolymer having a large bulk density, a uniform particle size with few fine particles, and a narrow molecular weight distribution. Further, the copolymer has a narrow composition distribution.
