Tri-Me glycine (TMG), a natural product found in plants as well as in humans, was demonstrated to be an efficient catalyst for the ring-opening polymerization (ROP) of cyclic carbonate, enabling the environmentally benign synthesis of aliphatic polycarbonate (APC). The ROP of trimethylene carbonate (TMC) using TMG proceeded under the bulk condition at 70 °C to give poly(trimethylene carbonate), possessing controlled mol. weight (∼4000) and low dispersity (∼1.22). The results of a matrix-assisted laser desorption/ionization time-of-flight mass spectral anal. and a chain extension experiment confirmed the controlled/living nature of the present ROP system, where side reactions, such as inter- and intramol. transesterifications, were minimized during the polymerization The screening of TMG analogs as a catalyst for ROP revealed that the combination of the carboxylate and quaternary ammonium moieties in TMG is an essential structural requirement. The Fourier transform IR analyses of TMC and alc. initiator in the presence/absence of TMG confirmed the biactivation property of the TMG. End-functionalized APCs were obtained using alc. initiators bearing clickable functionalities, such as azido and ethynyl groups. Furthermore, we demonstrated the synthesis of APC-diol and -triol, which can be used as prepolymers for APC-based polyurethane.
