Latest Patents

Sasaki's latest patents include an innovative method titled "Process for polymerization of olefins and catalyst composition therefor." This process presents an improved approach to polymerizing olefins utilizing a catalyst that consists primarily of two components:

A. A titanium trichloride composition that is obtained by micro-pulverizing a titanium trichloride component, prepared through the reduction of titanium tetrachloride. This process involves a member selected from a group of reducing agents including hydrogen, silicon, metallic titanium, and metallic aluminum. It incorporates a complex of aluminum chloride or aluminum bromide combined with an electron-donor sourced from oxygen-containing, nitrogen-containing, or phosphorus-containing organic compounds. The required amount of the complex is between 0.005 to 0.5 mole for every mole of the titanium trichloride component. The micro-pulverized titanium trichloride is then extracted using a solvent chosen from saturated aliphatic hydrocarbons, aromatic hydrocarbons, and halogenated aromatic hydrocarbons.

B. An organoaluminum compound is also employed in this catalyst composition, enhancing the efficiency of the polymerization process.
