Abstract
ABSTRACTThree‐arm star aliphatic polycarbonates (TMP‐PDTCs) were successfully synthesized via the ring‐opening polymerization of 2,2‐dimethyl trimethylene carbonate (DTC) initiated by trimethylolpropane (TMP) in the absence of catalysts. The structure of TMP‐PDTCs was characterized by Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and gel permeation chromatography (GPC). The effects of reaction temperature, time, and the DTC/TMP molar feed ratio on the non‐catalyst polymerization were investigated. The thermal behaviors of TMP‐PDTCs were measured by differential scanning calorimetry (DSC). © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41998.
