| 中文摘要 | chloro( 5,10,15,20-tetraphenyl-porphyrinato)-aluminum/tetraethylammonium bromide ( et4nbr) in combination with bulky lewis acid was used for the copolymerization of co2 and cyclohexene oxide ( cho). bulky lewis acid having substituents at the ortho positions of the phenolate ligands, like methylaluminum bis(2,6-di-tert-butyl-4-methylphenolate), significantly shortened the induction period and raised the catalytic activity, the corresponding turnover frequency reached 44.9 h(-1) in 9 h, which was 23.8% higher than that from ( tpp)alcl/et4nbr binary catalyst. the resulting polycarbonate has carbonate linkage over 93% with number average molecular weight of ( 4.5-6.5) x 10(3) and polydispersity index below 1.10. |
