Description

Be used to prepare the diol ester compound of olefin polymerization catalysis
Technical field
The present invention relates to a kind of new dibasic alcohol ester compound, the preparation method of this compound and this compound are used being used for preparing olefin polymerization catalysis.
Technical background
As everyone knows, with magnesium, titanium, halogen and electron donor solid titanium catalyst component, can be used for CH as basal component 2=CHR olefinic polyreaction, particularly in alpha-olefine polymerizing, can obtain the polymkeric substance of higher yields and higher tacticity with 3 carbon or more carbon atoms, wherein the electron donor compound is one of requisite composition in the catalyst component, and along with the development of internal electron donor compound has caused polyolefin catalyst constantly to update.At present, multiple electron donor compound is disclosed in a large number, for example polycarboxylic acid, monocarboxylic ester or multi-carboxylate, acid anhydrides, ketone, monoether or polyether, alcohol, amine etc. and derivative thereof, wherein comparatively commonly used is aromatic carboxylates's class of binary, for example n-butyl phthalate or diisobutyl phthalate etc. can be referring to U.S. Pat 4784983.
In recent years, the electron donor that people attempt to adopt other compound to be used as in the olefin polymerization catalyst components again uses, for example at U.S. Pat 4971937 and the European patent EP 0728769 disclosed catalyst component that is used for olefinic polyreaction, special 1 of two ether groups that contain have been adopted, the 3-diether compound is as electron donor, 2-sec.-propyl-2-isopentyl-1 for example, 3-Propanal dimethyl acetal, 2,2-diisobutyl-1,3-Propanal dimethyl acetal and 9,9 '-two (methoxymethyl) fluorenes etc.At the disclosed ingredient of solid catalyst that is used for olefinic polyreaction of Chinese patent CN1054139A, adopted special 1 of two ketone groups that contain, the 3-cyclohexadione compounds is as electron donor, for example 2,2 ', 4,6,6 '-pentamethyl--3,5-heptadione and 2,2 ', 6,6 '-tetramethyl--4-ethyl-3,5-heptadione etc.
The special dibasic aliphatic carboxylic acid ester compound of one class is disclosed again recently, as (referring to WO98/56830, WO98/56834, WO01/57099, WO01/63231 and WO00/55215) such as succinate, malonic ester, glutarates, the use of this class electron donor compound not only can improve activity of such catalysts, and the molecular weight distribution of gained propene polymer is obviously widened.
Yet, the above-mentioned disclosed binary aromatic carboxylic acid's ester compound of above-mentioned employing, contain 1 of two ether groups, the catalyzer that is used for olefinic polymerization of 3-diether compound and the preparation of dibasic aliphatic carboxylic acid ester compound all exists certain defective in actual applications, for example adopt the catalytic activity of catalyzer of binary aromatic carboxylic acid's ester compound lower, and the molecular weight distribution of resulting polymers is also narrower; Adopt 1, though the catalyzer of 3-diether compound is active higher, and catalyzer susceptibility that hydrogen is transferred might as well, the narrow molecular weight distribution of resulting polymers is unfavorable for the exploitation of the different trades mark of polymkeric substance; And adopt the catalytic activity of catalyzer of recent disclosed dibasic aliphatic carboxylicesters still on the low side, and when not adopting the external electron donor component, the degree of isotacticity of resulting polymers is lower.
The inventor has unexpectedly found a kind of polyol ester compound that contains special construction, when it uses as the electron donor in the olefin polymerization catalysis, can obtain the good comprehensive properties catalyzer, when being used for propylene polymerization, can obtain gratifying polymerization yield rate, and the stereospecificity of polymkeric substance is higher, even when not using external electron donor, still can obtain the polymkeric substance of higher degree of isotacticity, catalyzer is also better to the susceptibility of hydrogen accent simultaneously, the molecular weight distribution broad of resulting polymers helps the exploitation of the different trades mark of polymkeric substance.It can obtain still less gel content during especially for second third copolymerization at the copolymerization that is used for alkene in addition, therefore has better copolymerization performance.
