Abstract

Developing green and well-controlled polymerization methods is of great significance for the preparation of biomedical polymer materials.In this contribution,an efficient organocatalytic ring-opening polymerization(ROP)of a class of seven-membered cyclic carbonates(T6DO,T6HDO,C6DO,C6HDO)containing cis-or trans-cyclohexane structure was established.Organic catalyst 1,5,7-triazabicyclo[4.4.0]dec-5-ene(TBD)promoted living polymerization of these cyclic carbonates to deliver polycarbonate and block copolymer products with predictable molecular weights and narrow dispersity.The robust TBD-mediated ROP at 90 ℃ showcased turnover frequency(TOF)up to 103 h-1.The resulting amorphous polycarbonates displayed good thermal stability.
