The molecular weight distribution index of a prepared polymer is wider than that of a polymer prepared by using methyl cyclohexyl dimethoxy silane (CHMMS) as an external electron donor, and the olefin polymerization catalyst is conductive to polymer processing.
Description
Technical field
The present invention relates to a kind of catalyzer for olefinic polyreaction, more particularly, relate to and a kind ofly comprise solids containing titanium catalyst component, promotor and alkylene three hydrocarbyloxysilane compound and the composite catalytic systems for polymerization of olefins as external donor compound of alkyl two hydrocarbyloxysilane compound, belong to field of olefin polymerisation.
Background technology
As everyone knows, generally be made up of three parts for the catalyst system in the polyreaction of alpha-olefin and composition thereof, they are: (1) Primary Catalysts (solid catalyst), (2) promotor (being generally aluminum alkyls compounds) and (3) polymerization time the external donor compound that adds.
In polymerization process, use one or more external electronic donor compounds to control the taxis of polymkeric substance and form is that those skilled in the art are in common knowledge.External electron donor is except the taxis affecting polymkeric substance, the performance of the other sides such as the activity of catalyzer and hydrogen response can be had influence on to some extent toward contact, but while the effect that its impact is played often in one aspect, then can play side effect in other respects.Although there will be a known multiple compounds perhaps can as external electron donor, specific catalyzer uses different external donor compounds may produce different polymer performances.Select suitable external electron donor can be compatible especially with specific catalyzer.That is, find a kind of applicable external electron donor can improve some performance of polymeric articles significantly as activity, degree of isotacticity, molecular weight distribution and hydrogen response etc., and other performance do not affected simultaneously or affect very little, therefore find that one group of external electron donor that polymkeric substance can be made to have fine over-all properties for special catalyst is very favorable.
In European patent EP 385765A, describe a kind of catalyst system, this system is made up of the Ziegler-Natta catalyst mixed with two kinds of silane external electron donors, and a kind of embodiment of concrete external electron donor mixture is dicyclopentyl dimethoxyl silane and propyl-triethoxysilicane.In US Patent No. 5,100, in 981, disclose a kind of catalyst system, it is made up of the mixture of Primary Catalysts and two kinds of external electron donors, and described external electron donor is CHMMS and phenyl triethoxysilane.In Japanese Patent JP19820199728, also illustrate a kind of catalyst system, this system uses the Ziegler-Natta catalyst of two kinds of silane external electron donor mixing to form, and mentions methyl benzoate and tetraethoxysilane can be used as Mixed electron donor in patent; Japanese Patent JP19820174495; In JP19920331459, also using tetraethoxysilane as external electron donor, but net effect is all bad.
Chinese patent CN02100896.5, CN02100900.7, CN03109781.2, CN03140565.7, CN200410073623.8, CN200410073621.9 etc. describe and use polyol ester compounds and the composite catalyst component for internal electron donor of adjacent benzene dicarboxylic acid ester compound, when this catalyst component is used for propylene polymerization, external electron donor alkyl two hydrocarbyloxysilane used is current industrial conventional external electron donor, such as Cyclohexylmethyldimethoxysilane (CHMMS) etc.Although Chinese patent CN03109781.2 also using different external electron donors as a comparison, such as except using Cyclohexylmethyldimethoxysilane, second, isobutyl dimethoxy silane, dicyclopentyl dimethoxyl silane (DCPMS), two (cyclobutylmethyl) dimethoxysilane etc. are also used, but find from disclosed patent, the hydrogen response of this kind of catalyst system is poor.
How to keep with the feature of the polyol ester compounds catalyst system that is internal electron donor, improving orientation property and the hydrogen response of this catalyst system simultaneously, thus improve the over-all properties of catalyst system, is the important technological problems needing to solve.
The present inventor is surprised to find that in research work, the granulated ingredient of solid catalyst being internal electron donor using polyol ester compounds in olefinic polymerization time add alkylene three hydrocarbyloxysilane compound and composite orientation property and the hydrogen response improving catalyzer as external donor compound further of alkyl two hydrocarbyloxysilane compound.The molecular weight distributing index of the polymkeric substance obtained is wider as polymkeric substance during external electron donor than using Cyclohexylmethyldimethoxysilane (CHMMS), is conducive to polymer processing.
Summary of the invention
The object of the present invention is to provide a kind of catalyzer for olefinic polyreaction, this catalyzer has high polymerization activity, the degree of isotacticity that the polymkeric substance tool obtained is higher, and the hydrogen response of catalyzer improves greatly simultaneously.
