Development of Ester Free Type Poly(trimethylene carbonate) Derivatives with Pendant Fluoroaromatic Groups

摘要

The facile method for the synthesis of ester free type poly(trimethylene carbonate) (PTMC) derivatives is previously reported. In this paper, a series of PTMC derivatives with fluoroaromatic groups in the side chain are synthesized to improve polymer properties. Thermal analysis reveals that all the PTMC derivatives have a decomposition temperature exceeding 300 °C. Furthermore, as the number of fluorine attached to the aromatic ring increases, the glass transition temperature decreases. In order to clarify the surface properties of their films, the contact angles and protein adsorption are evaluated. The hydrophobic nature is attributed to the fluorine groups at the side chain. Furthermore, it is suggested that as the number of fluorine attached to the aromatic ring increases, the protein adsorption is suspended. There is a possibility that a new biomaterial could be created by introducing a fluoroaromatic group into the side chain of PTMC with ester free structure.
