POLYMERIZATION OF PROPYLENE

摘要

PURPOSE:To produce a highly crystalline PP excellent in physical properties, by polymerizing propylene using a catalyst which consists of a titanium halide on a specific carrier with an organic aluminum compound. CONSTITUTION:In the process of polymerizing propylene using a catalyst comprising a transition metal catalyst and an organic aluminum compound, a solid catalyst produced by supporting a titanium halide on a carrier comprising talc and a magnesium halide is used as the transition metal catalyst. The use of the above catalyst produces a highly crystalline PP excellent in physical properties.
