Catalyst for olefin polymerization with high isotactic index
A recently granted patent (Publication Number: US11970510B2) discloses a catalyst component for olefin polymerization that includes magnesium, titanium, a halogen, and an internal electron donor. The internal electron donor consists of a monocarboxylic ester compound and a diether compound, with a specific molar ratio between the two compounds. The catalyst component is produced from a reaction involving a magnesium source containing sulfur, a titanium source, and the internal electron donor. The magnesium source is prepared using a specific method involving elemental sulfur, a magnesium halide, a compound, and an optional inert liquid medium and surfactant. The resulting catalyst component exhibits a precise weight ratio of titanium, magnesium, halogen, and internal electron donor elements.
Furthermore, the patent also covers a catalyst for olefin polymerization that includes the aforementioned catalyst component, at least one alkyl aluminum compound, and an optional external electron donor compound. An olefin polymerization method using this catalyst involves contacting the olefin under specific conditions. The patent details various formulas and compounds involved in the catalyst component, highlighting the specific characteristics and ratios required for optimal performance. The disclosed invention aims to provide an efficient catalyst system for olefin polymerization, enhancing the process's effectiveness and productivity in the polymer industry.
