Abstract

The invention relates to a non-metallocene catalyst containing a product obtained after contact between a non-metallocene complex and aluminoxane. The invention also relates to a manufacturing method of the non-metallocene catalyst and its application in olefin polymerization. In comparison with simple merging of the non-metallocene complex and aluminoxane, the non-metallocene catalyst shows a raised polymerization activity. The non-metallocene catalyst is especially suitable to be used as a catalyst for copolymerization of ethene and cycloolefin so as to manufacture an ethene-cycloolefin copolymer.

Description

technical field [0001] The present invention relates to a non-metallocene catalyst, especially a non-metallocene catalyst comprising the contact product of a non-metallocene complex and an aluminoxane. The invention also relates to the production method of the non-metallocene catalyst and its application in olefin polymerization. Background technique [0002] With the continuous progress of society and the rapid development of science and technology, the demand for high-performance materials is also increasing. Ethylene-cycloolefin copolymer is an excellent amorphous thermoplastic polymer material. As one of the high-end products of the C5 series of comprehensive utilization, it has the characteristics of high transparency, low water absorption, high heat resistance and high refractive index, and is expected to replace PC and PMMA in optical components. In addition, this material may also have a potentially huge market in the fields of packaging, electronic components, med...
