ABSTRACT:
A heterogeneous catalyst system comprising a novel titanium catalyst component, the product of a sequential reaction of titanium halide with carbodiimide compound and an organometallic aluminum compound, supported on such an inorganic carrier as magnesium halide and an organometallic aluminum cocatalyst component which is not methylaluminoxane, and a process for polymerization of olefin using the said catalyst system. The catalyst system has an excellent (co)polymerization properties and produces copolymers having a narrow compositional distribution, a broad molecular weight distribution and excellent morphological properties such as spherical shape and a high bulk density.
