英文摘要 | a one-pot synthesis of oligo(carbonate-ether) triol was realized by the copolymerization of co2 and propylene oxide (po) using a zinc-cobalt double metal cyanide (zn-co-dmc) catalyst in the presence of 1,3,5-benzenetricarboxylic (trimesic) acid (tma). the catalytic activity ranged from 0.3 to 1.0 kg g(-1) dmc under various copolymerization conditions. the structure of the oligo(carbonate-ether) triol was clearly confirmed, providing sound evidence for the special role played by the tma, i.e., that it acted as an initiation-transfer agent. in the first stage the tma initiated po homo-polymerization to afford oligo-ether triol via a core-first approach in the presence of zn-co-dmc. after all of the tma was consumed, the in situ formed oligo-ether triol acted as new chain transfer agent to participate in the copolymerization, forming carbonate-ether segments and therefore the oligo(carbonate-ether) triol. since every molecule of tma participated in initiation and propagation steps, the molecular weight of the triol depended on the amount of tma used rather than the amount of zn-co-dmc. consequently, the number average molecular weight (m-n) of the oligo(carbonate-ether) triol could be well controlled from 1400 to 3800 g mol(-1) with a relatively narrow polydispersity index (pdi) (1.15-1.45), and its carbonate unit content (cu) could be adjusted between 20% and 54%. |
