摘要：Polymerization of mixed alpha-olefins originating from the Fischer-Tropsch synthesis catalyzed by theBu)_3/[Me_2NHPh]^+[B(C_6F_5)_4]^-,was studied.The effects of the Zr/olefin mole ratio,Al/Zr mole ratio,reaction temperature,and reaction time on the viscosity and molecular weight of the product were investigated.The conversion under optimized conditions reached 97.3%.The product structure was characterized by ^(13)C NMR spectrometry and ~1H NMR spectrometry,and the conversion of olefins with different carbon numbers under different conditions was determined by GC analysis.The polymer obtained under optimized conditions has a high viscosity index of 262 with a narrow molecular weight distribution of 1.95,which is a desired component for lubricating base oil.
Polymerization of mixed alpha-olefins originating from the Fischer-Tropsch synthesis catalyzed by the metallocene catalyst system, rac-Et(1-Ind)(2)ZrCl2/Al(iBu)(3)/[Me2NHPh](+) [B(C6F3)(4)](-), was studied. The effects of the Zr/olefin mole ratio, Al/Zr mole ratio, reaction temperature, and reaction time on the viscosity and molecular weight of the product were investigated. The conversion under optimized conditions reached 97.3%. The product structure was characterized by H-13 NMR spectrometry and H-1 NMR spectrometry, and the conversion of olefins with different carbon numbers under different conditions was determined by GC analysis. The polymer obtained under optimized conditions has a high viscosity index of 262 with a narrow molecular weight distribution of 1.95, which is a desired component for lubricating base oil.
