Technical field

The present invention relates to a kind of non-metallocene catalyst.Specifically, 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, also known as post-metallocene catalysts, the central atom of Primary Catalysts includes nearly all transition metal, reach at some aspect of performance, even exceed metallocene catalyst, become the forth generation olefin polymerization catalysis after Ziegler, Ziegler-Natta and metallocene catalyst.According to the difference of the central atom of Primary Catalysts, non-metallocene (IIIB race, IVB race, VB race, group vib, VIIB race) catalyzer and non-luxuriant rear transition metal (VIII) catalyzer can be divided into again further.The excellent property of the polyolefin products manufactured by such catalyzer, and low cost of manufacture.Non-metallocene catalyst ligating atom is oxygen, nitrogen, sulphur and phosphorus, not containing cyclopentadienyl group or its deriveding group, as indenyl and fluorenyl etc., it is characterized in that central ion has stronger Electron Affinities, and there is cis alkyl or halogen metal division center, easily carry out alkene to insert and σ-key transfer, the easy alkylation of central metal, is conducive to the generation at cation activity center; The title complex formed has the geometric configuration of restriction, and stereoselectivity, electronegativity and chirality controllability, in addition, the metal-carbon key formed easily polarizes, and is more conducive to polymerization and the copolymerization of alkene.Therefore, even if the olefin polymer of higher molecular weight also can be obtained under higher polymeric reaction temperature.

But homogeneous catalyst has been proved it in olefinic polyreaction has that active duration is short, easily sticky still, high methylaluminoxane consumption, 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/copolymerization catalyzer or catalyst system, there is alkene homopolymerization/copolymerization performance widely, but the catalyzer disclosed in this patent or catalyst system in olefinic polymerization time need higher promotor consumption, suitable olefin polymerizating activity could be obtained, and it is short to there is active duration in polymerization process, polymkeric substance glues the phenomenons such as still.

Common way be by non-metallocene catalyst by certain supported technology, make loaded catalyst, thus improve the polymerization of alkene and the particle form of resulting polymers.It shows as the initial activity suitably reducing catalyzer to a certain extent, the polymerization activity life-span of extending catalyst, reduce the caking or cruelly poly-phenomenon that even avoid in polymerization process, improve the form of polymkeric substance, improve the apparent density of polymkeric substance, it can be made to meet more polymerisation process, as vapour phase polymerization or slurry polymerization etc.

Existing olefin polymerization catalysis patent is mostly based on metallocene catalyst, as US 4808561, US 5240894, CN 1344749A, CN 1126480A, ZL94101358.8, CN 1307594A, CN 1103069A, CN1363537A, US6444604, EP0685494, US4871705 and EP0206794 etc., but these patents also all relate to and being carried on the carrier after process by the metallocene catalyst containing transition metal.
