  • Alkoxy magnesium supported olefin polymerization catalyst component, catalyst and application thereof
    Patent number: 11124583
    Abstract: Provided is an alkoxy magnesium supported olefin polymerization catalyst component, comprising the reaction products of the following components: at least one alkoxy magnesium compound of Mg(OR1?)N(OR2?)2-N, at least one titanium compound of general formula Ti(OR)nX4-n, at least one ortho-phenylene diester electron donor compound a, and at least one diether electron donor compound b, wherein the molar ratio of a to b is 0.05 to 20. The catalyst component has an ultrahigh polymerization activity when used for olefin polymerization, and does not require the use of an external electron donor, but can also obtain a polymer with a high isotacticity, and the resulting polymer has a relatively wide molecular weight distribution and a relatively low ash content.
