Title: Polymerization of propylene
Inventor: ASANUMA TADASHI
IPC: C08F10/06
Filed: 1983-04-12
Abstract: PURPOSE:To obtain polypropylene in high yields per unit weight of catalyst, by polymerizing zeolite-treated propylene, alone or together with other alpha-olefins, in the presence of a Ziegler-Natta catalyst. CONSTITUTION:In producing stereoregular polypropylene by polymerizing propylene, alone or together with other alpha-olefins, in the presence of a Ziegler-Natta catalyst comprising a titanium halide and an organoalminum compound, the propylene monomer consists of propylene treated with zeolite of a pore size of 3-9Angstrom . Especially when a catalyst obtained by impregnating magnesium cyloride with titanium chloride is used as the Ziegler-Natta catalyst, the effect is remarkable. Commercially available zeolite can be used as such or after firing at a suitable temperature (e.g., 350 deg.C).
