Technical field

The present invention relates to a kind of non-metallocene catalyst.Particularly, the present invention relates to a kind of load type non-metallocene catalyst, its preparation method and the application in alkene homopolymerization/copolymerization thereof.

Background technology

The non-metallocene catalyst that middle and later periods nineteen nineties occurs, because non cyclopentadienyl catalyst appears on the time after the metallocene catalyst, " after luxuriant " olefin polymerization catalysis therefore is otherwise known as.It has the characteristics similar to metallocene catalyst, can customize as required polymkeric substance, and cost is lower.The central atom of non-metallocene catalyst has comprised nearly all transition metal, reaches at some aspect of performance, even surpasses metallocene catalyst, becomes the olefin polymerization catalysis of new generation after Ziegler-Natta and metallocene catalyst.According to the difference of the central atom of Primary Catalysts, further can divide into again non-metallocene (IIIB family, IVB family, VB family, group vib, VIIB family) catalyzer and non-luxuriant rear transition metal (VIII family) catalyzer.By the excellent property of the polyolefin products of such catalyzer manufacturing, and low cost of manufacture.The non-metallocene catalyst ligating atom is oxygen, nitrogen, sulphur and phosphorus, do not contain cyclopentadienyl group or its deriveding group, such as indenyl and fluorenyl etc., it is characterized in that central ion has stronger Electron Affinities, and have cis alkyl or halogen metal division center, easily carry out alkene insertion and σ-key and shift, the easy alkylation of central metal is conducive to the generation at cation activity center; The title complex that forms has the geometric configuration of restriction, stereoselectivity, electronegativity and chirality controllability, and in addition, formed metal-carbon key easily polarizes, and more is conducive to polymerization and the copolymerization of alkene.Therefore, even under higher polymeric reaction temperature, also can obtain the olefin polymer of higher molecular weight.

But homogeneous catalyst has been proved it in olefinic polyreaction has that active duration is short, easily sticking still, methylaluminoxane consumption are high, and obtain the too low or too high weak point of polymericular weight, only can be used for solution polymerization process or high-pressure polymerization process, seriously limit its industrial applicability.

Patent ZL 01126323.7, ZL 02151294.9ZL 02110844.7 and WO 03/010207 disclose a kind of alkene homopolymerization/catalyst for copolymerization or catalyst system, has widely alkene homopolymerization/copolymerization performance, but need higher promotor consumption during in olefinic polymerization at the disclosed catalyzer of this patent or catalyst system, could obtain suitable olefin polymerizating activity, and it is short to exist active duration in the polymerization process, the phenomenons such as the sticking still of polymkeric substance.

Common way be with non-metallocene catalyst by certain load technology, make loaded catalyst, thereby improve the polymerization of alkene and the particle form of resulting polymers.It shows as the initial activity that has suitably reduced to a certain extent catalyzer, the polymerization activity life-span of extending catalyst, reduce even avoided caking or the cruelly poly-phenomenon in the polymerization process, improve the form of polymkeric substance, improve the apparent density of polymkeric substance, can make it satisfy more polymerization technique process, such as vapour phase polymerization or slurry polymerization etc.

For patent ZL 01126323.7, the disclosed non-metallocene catalyst of ZL 02151294.9ZL 02110844.7 and WO03/010207, patent CN 1539855A, CN 1539856A, CN 1789291A, CN 1789292A, CN 1789290A, WO/2006/063501, ZL200510119401.x etc. provide various ways to carry out load to obtain load type non-metallocene catalyst, but these patents all relate to the Nonmetallocene organic compound that will contain transition metal and (or are called non-metallocene catalyst, or Nonmetallocene title complex) is carried on the carrier after the processing, the non-metallocene catalyst charge capacity is lower, or it is combined not bery tight with carrier.

Patent 200710162667.1,200710162676.0,200910210987.9 and 200910210991.5 disclosed load type non-metallocene catalyst patents provide and have not contained porous oxide, and single Catalysts and its preparation method take magnesium compound as carrier.Because do not have the adding of porous oxide carrier, the catalytic performance of load type non-metallocene catalyst has obtained fully playing, polymerization activity is higher.But this class catalyzer adopts the method for vacuum-drying or solvent deposition in the carrier moulding process, is difficult to control moulding process and the particle form of carrier, so the difficult control of the form of polymkeric substance.

Catalyzer take Magnesium Chloride Anhydrous as carrier demonstrates higher catalytic activity in olefin polymerization process, but this type of catalyzer is highly brittle, and is easily broken in polymerization reactor, thereby causes polymer morphology bad.Silicon dioxide carried catalyzer has good flowability, can be used for gas fluidised bed polymerisation, but silicon dioxide carried metallocene and non-metallocene catalyst then show lower catalytic activity.Therefore if magnesium chloride and silicon-dioxide are well organically combined, just may prepare and have high catalytic activity, the catalyzer of the controlled and good abrasion strength resistance of globule size.

Patent CN200610026765.8 discloses a class single active center Z-N olefin polymerization catalysis.This catalyzer with the salicylaldehyde derivatives of the salicylic aldehyde that contains coordinating group or replacement as electron donor, by in magnesium compound (such as magnesium chloride)/tetrahydrofuran solution, adding through pretreated carrier (such as silica gel), metallic compound (such as titanium tetrachloride) and this electron donor obtain after the processing.Because having adopted in type porous support as the skeleton of complex carrier in the catalyst preparation process, the form of catalyzer is easier to control, and the form of polymkeric substance also makes moderate progress.

The magnesium halide that generates in the chemical reaction process also can prepare as carrier the olefin polymerization catalysis of load, and can regulate by the control chemical reaction process formation speed of magnesium halide, realizes morphology Control to magnesium halide carrier with this.And studies show that the magnesium halide that is generated by Grignard reagent and halide reaction has higher specific surface, and unordered crystalline structure (Eur Polym J, 2000,19:19), be suitable for preparing loaded catalyst.

Japanese Patent JP1054005A, JP1054006A and JP63186706A provide the method for preparing high activity olefin polymerization catalyst, it is to make Grignard reagent MgRX (R is alkyl, X is halogen) obtain the magnesium compound carrier with halohydrocarbons reaction, then magnesium halide carrier load halogenated titanium is made loaded catalyst, and the activity of this catalyst olefinic polymerization is higher.

Japanese Patent JP 1081803A provides a kind of method for preparing olefin polymerization catalysis, it is to make Grignard reagent MgRX (R is alkyl, X is halogen) generate magnesium halide carrier with halogenated compound (such as aluminum chloride) reaction, then magnesium halide carrier load halogenated titanium is made loaded catalyst.
