Catalysts and processes for the polymerization of olefins

Public has for olefin aggregate of catalyst, it including following material reaction of product: (a,) a titanium, and zirconium or hafnium of bridge even of and/or replaced of ring e II Ene base compounds; (b) a has formula (II) Al (CH2-CR4R5R6) wR7yHz of organic aluminum compounds, type in the of the (CH2-CR4R5R6) group can same or different, R4 is with 1 to 10 a carbon Atomic of alkyl, and Ene base or Fong alkyl, R5 is containing 3 to 50 a carbon Atomic and different Yu straight chain alkyl or vinyl base of alkyl, and vinyl base, and aryl, and Fong alkyl or n-aryl, and optimization to, R4 and R5 heavy-in in together can formed a containing 4 to 6 a carbon Atomic of ring, R6 is hydrogen or containing 1 to 10 a carbon Atomic of alkyl, and vinyl base or Fong alkyl, all R7 replaced base can same or different, is containing 1 to 10 a carbon Atomic of alkyl, and vinyl base, and aryl, and Fong alkyl or n-aryl, and any selected to, can containing silicon or germanium Atomic, w is 1,2 or 3 , Z is 0 or 1,y=3-w-z; and (c) of water. Aluminium/between shuimoerbi and 1:1. Known uses are different from catalyst for Aluminide based on comparing these catalysts showed higher activity.
