Blends of maleic anhydride endcapped poly(propylene carbonate)(MAPPC) with ethylcellulose(EC) in different mass fraction composition were prepared by solution casting. DSC, TGA, WAXD and SEM were used to investigate the miscibility, thermal stability, aggregation structure and morphology of the blends. A single glass transition temperature of the blend revealed the miscibility of MAPPC with EC in the noncrystalline region. The solid phase-mesophase phase transition temperature, the mesophase-isotropic phase transition temperature and the transition enthalpy of the blends were found increased gradually with the increase of EC content in the EC-rich blend. Upon blending EC into MAPPC, the thermal decomposition temperatures were elevated, especially for MAPPC/EC blend with mass ratio of 90:10. Dilution of MAPPC with cholesteric liquid crystalline EC caused the shift of two peaks of EC to greater Bragg angles and the decrease of the distances between layers of ordered polymer chains and the distances between polymer chains, and resulted in the increase of crystallite dimensions of mesophase region and the decrease of sizes of non-crystalline region. Blends appeared to pack more compactly.
