| titleOfInvention | Catalyst component used for vinyl polymerization, preparation method and application |
| abstract | The invention provides a titaniferous solid catalyst component used for vinyl polymerization and a preparation method. The titaniferous solid catalyst component is prepared according to the following three continuous steps: 1) under the existence of halogen or halogen-containing compound, reacting metal magnesium with alcohol, thereby preparing a magnesium-containing solid; 2) utilizing an organic metallic compound or a mixture of the organic metallic compound and an electron donor compound to process the magnesium-containing solid, thereby obtaining a magnesium-containing catalyst carrier; and 3) under the existence of an inert organic solvent, utilizing a compound of transition metal titanium to process the magnesium-containing catalyst carrier, and then utilizing a halogenated alcohol compound to process, thereby obtaining the catalyst component. The preparation method has the characteristics of simple process, convenience in operation, low investment in industrial equipment, easiness in controlling the product quality, and the like. The titaniferous solid catalyst component has the characteristics of high vinyl polymerization catalytic activity, high copolymerizing capacity, high stacking density of polymer, less subdivision, and the like. The titaniferous solid catalyst component is suitable for slurry polymerization or gas-phase polymerization of vinyl, and is especially suitable for a gas-phase fluidized bed polymerization process for the vinyl, in which the catalyst is fed in a slurry form. |
