Abstract
AbstractIn order to tune the thermal properites of ester‐free type poly(trimethylene carbonate) (PTMC) derivatives, the copolymers of trimethylene carbonate (TMC) and a TMC derivative bearing a triphenylmethyl group (TrTMC) were synthesized with various copolymerization ratios. The copolymers of TMC and TrTMC were obtained by varying the feeding ratio of their monomers with good yields as hexane‐isopropanol (9/1, v/v) insoluble part. The structures were confirmed by both FT‐IR and 1H NMR spectra, showing the copolymer composition was controlled in a good manner. The thermal degradation temperature at 10 % weight loss gradually increased from 198 °C to 301 °C, depending on the introduced amount of TrTMC, indicating that the thermal decomposition was based on the monomer unit structure. The glass transition temperatures of copolymers also gradually increased from −38 °C to 57 °C. These results show that the thermal properties of the ester free type TMC derivatives could be overcome by the copolymerization, and that the thermal properties could be varied by controlling the feed ratio of comonomers.
