摘要

Four kinds of AliBu2OB' with different R' were synthesized. The effect of AliBu2OR'/AliBu3 mole ratio on the conversion

the [η] of copolymer and catalytic efficiency were studied. The conversion was increased obviously and the catalytic efficiency was 2.7 times higher than before. The effect of the amount of AliBu2OR' on the valence state of vanadium ion and the change of the valence state of vanadium ion with reaction temperature and time were studied. The VIS and IR spectra of the trinary-component catalyst system were measured.The model of active center including AliBu2OR' was proposed.The function of AliBu2OR was explained.
