Abstract

The synthesis of polyethylene glycol (PEG) and poly(trimethylene carbonate) PTMC block copolymers via living ring-opening polymerization (ROP) of trimethylene carbonate (TMC) with PEG in the presence of HClEt₂O as a monomer activator was investigated. The TMC conversion and molecular weight of PTMC were found to be increasing linearly with the polymerization time. Increasing the feed ratios of TMC to MPEG led to PDI decreasing, because of no chain transfer such as backbiting reaction. The diblock copolymers obtained by the polymerization exhibited characteristic peaks of PTMC and carbitol or MPEG. The obtained PTMC had molecular weight close to the theoretical values calculated from PMC/PEG molar ratios and exhibited a monomodal GPC curve without any trace of dead polymer.
