Abstract

The present invention relates to a cocatalyst composition and application thereof, in particular to a cocatalyst composition. The cocatalyst is characterized by comprising a reaction product of alkylaluminium and water, and alkyl aluminum, wherein based on A1, the molar ratio of the reaction product of the alkylaluminium and the water to the alkyl aluminum is 0.5: 1 to smaller than 4: 1. The present invention further relates to a catalyst system containing the cocatalyst composition, and application of the cocatalyst composition in non-metallocene complexe catalyzed chain alkene-cycloalkene copolymerization. Compared with the alkyl aluminum, the cost of the cocatalyst composition disclosed by the present invention is lower.

Description

technical field [0001] The invention relates to a cocatalyst composition, which is especially suitable for the copolymerization reaction of alkenes and cycloalkenes catalyzed by non-metallocene complexes. The present invention also relates to the catalyst system comprising the cocatalyst composition, the application of the cocatalyst composition in non-metallocene complex-catalyzed alkene-cycloolefin copolymerization and the alkene and cycloolefin co-catalyzed by the cocatalyst composition Copolymerization of olefins. 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. Olefin-cycloolefin copolymers, especially ethylene-cycloolefin copolymers, are excellent amorphous thermoplastic polymer materials with high transparency, low water absorption, high heat resistance and high refractive index. As one of the high-end products of C5 series comprehe...
