제목 Alternating ring-opening copolymerization of epoxide and anhydride using a chromium complex with a sterically demanding amino triphenolate ligand
초록 We have investigated alternating ring-opening copolymerization (ROCOP) of epoxides (limonene oxide, cyclohexene oxide) with anhydrides (phthalic anhydride, naphthalic anhydride and maleic anhydride) using a chromium complex containing sterically-demanding amino triphenolate ligand. The polymerization reactions were strongly affected by the type and the amount of co-catalyst, reaction time, and feed ratio of monomers. Under the optimized conditions, the chromium complex produced perfectly alternating polyesters with high molecular weights, high glass-transition temperatures, and low polydispersity. It also showed a very high activity (TOF up to 380 h −1 ).
