摘要

Abstract Chloro(5

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) × 103 and polydispersity index below 1.10.
