2Application in the polyreaction of=CHR and composition thereof, wherein R is the alkyl of hydrogen or 1～12 carbon atom.More particularly, relate to a kind of catalyst component and catalyzer and application thereof that contains at least two kinds of electron donor compounds.
Technical background
Containing the titanium compound that is loaded on the magnesium halide in active and the catalyzer of electron donor compound is well known in the prior art.
U.S. Pat 4544717 discloses, and by add electron donor compound (being the internal electron donor compound) in the solid ingredient that contains titanium compound, can improve the stereospecificity of catalyzer.Up to now, existing many patent disclosures the multiple internal electron donor compound that is applicable to the preparation Ziegler-Natta catalyst, and the catalyzer that is used for olefinic polymerization that comprises these internal electron donor compounds.
These internal electron donor compounds mainly comprise: the electron donor compound of European patent EP 0045977 described phthalate, European patent EP 0361493, describe among the EP0728724 1, the 3-diether compound, describe among the Chinese patent CN1105671A 1, the 3-cyclohexadione compounds, Chinese patent CN1236732, CN1236733, CN1236734, the malonic ester compounds of the special replacement of describing among the CN1292800, the succinate compounds of describing in the PCT International Application No. WO 0063261, the beta substitution glutarate compounds of describing in the PCT International Application No. WO 0055215, the cyano group ester compound of describing among the Chinese patent CN1242780, the two amine electron donor compounds of describing among the Chinese patent CN1087918, the electron donor compound of the maleic acid ester class of describing in the PCT International Application No. WO 03022894, and Chinese patent CN1436766A, a kind of special polyol ester compounds of describing among the CN1436796A etc.
Owing to adopt different internal electron donor compounds to make prepared catalyzer have different characteristics, for example some catalyzer has higher activity, some catalyzer has better hydrogen regulation sensitivity, the polyolefin resin of some Preparation of Catalyst has wider molecular weight distribution or the like, but in polyolefinic industrial production, be starved of the employed catalyzer of polymerization and have very excellent comprehensive performances.In the prior art, people adopt the method that adds multiple internal electron donor compound in catalyst preparation process to improve the over-all properties of catalyzer usually.In disclosed patent WO9957160, WO0230998, WO03002617, JP2001139621, JP2002249507, KR20000026517 etc., set forth and used two or more internal electron donor compound to prepare catalyst component and the catalyzer that is used for olefinic polymerization simultaneously.But its result can't be satisfactory.。Usually, owing to after having used two or more internal electron donor compounds,, activity of such catalysts is decreased though molecular weight distribution that can resulting polymers broadens.
By repetition test, the inventor finds by selecting for use two kinds of internal electron donor compounds to use jointly at least, and wherein a kind of be polyol ester compound with special construction, can prepare the catalyst component and the catalyzer of high comprehensive performance.It is worthy of note that catalyzer of the present invention is being used for olefinic polymerization, is particularly showing very high activity and wider molecular weight distribution during propylene polymerization.
