Date Jul. 14, 1988.This invention is a catalyst for polymerization of olefins, comprising a compound of a transition metal of Group IVB of the periodic table, an aluminoxane and a particulate organic or inorganic compound carrier. This catalyst shows very high activity in the polymerization and copolymerization of olefins and gives polymers having a high bulk density, a uniform particle size, a low content of fine particles and a narrow molecular weight distribution and in the case of copolymers, a narrow composition distribution as well. |
