Abstract
The invention relates to a catalyst component for olefin polymerization, a catalyst and an olefin polymerization method. The catalyst component for olefin polymerization comprises magnesium, titanium, halogen and an internal electron donor, wherein the internal electron donor comprises a cyclic compound shown in a formula I and a diol ester compound shown in a formula Z. When the olefin polymerization catalyst component is used for propylene polymerization, the hydrogen regulation sensitivity of the catalyst is good, the isotactic index of the obtained polymer is adjustable, and the molecular weight distribution of the obtained polypropylene resin is wide.
Description
Technical Field
The invention relates to a catalyst component for olefin polymerization, a catalyst and an olefin polymerization method.
Background
Olefin polymerization catalysts can be divided into three broad categories, namely, traditional Ziegler-Natta catalysts, metallocene catalysts, and non-metallocene catalysts. For the conventional Ziegler-Natta catalysts, polyolefin catalysts are continuously updated with the development of electron donor compounds in the catalysts. Development of the catalyst from the first TiCl3AlCl3/AlEt2Cl system and second generation of TiCl3/AlEt2Cl system, magnesium chloride of the third generation as a carrier, monoester or aromatic dibasic acid ester as an internal electron donor, and TiCl with silane as an external electron donor4·ED·MgCl2/AlR3The catalytic polymerization activity of the catalyst and the isotacticity of the obtained polypropylene are greatly improved by an ED system. In the prior art, a titanium catalyst system for propylene polymerization mostly uses magnesium, titanium, halogen and an electron donor as basic components, wherein the electron donor compound is one of the essential components in the catalyst component. Eyes of a userPreviously, various electron-donor compounds have been disclosed, such as mono-or polycarboxylic acid esters, anhydrides, ketone 12/monoethers or polyethers, alcohols, amines, etc., and derivatives thereof, among which aromatic dicarboxylic acid esters (such as di-n-butyl phthalate or diisobutyl phthalate, etc., see US4784983) are more commonly used. Due to the limited use of phthalate compounds in the EU, novel electron donor compounds such as 1, 3-diether compounds containing two ether groups [ e.g. 2-isopropyl-2-isopentyl-1, 3-dimethoxypropane, 2-diisobutyl-1, 3-dimethoxypropane and 9, 9-bis (methoxymethyl) fluorene ] have been developed for environmental protection, see US4971937 and EP0728769]And dibasic aliphatic carboxylic acid ester compounds (e.g. succinate, malonate, glutarate, etc., see patents WO98/56830, WO98/56834, WO01/57099, WO01/63231 and WO00/55215), and glycol ester compounds (see patents CN1436766A, CN1453298A, etc.). In recent years, many novel internal electron donor compounds containing nitrogen atom structures, such as maleic amide internal electron donor compounds (CN102268109), hydrazide internal electron donor compounds (CN103539874), diamide internal electron donor compounds (US2017/0240667), carbamate internal electron donor compounds (WO2014/048861) and amide ester internal electron donor compounds of dow ring ball technology ltd (US2012322962), have emerged, but the overall effect of the obtained catalyst is not outstanding.
The present inventors have found and synthesized a novel organic compound having a cyclic structure, and have found that when the novel compound having a cyclic structure is added to prepare a catalyst for olefin polymerization, a catalyst having excellent overall properties can be obtained, and when the catalyst is used for propylene polymerization, a polymer having a high molecular weight distribution and a high melt index can be obtained.
