Two series of renewable nipagin and eugenolbased copoly(ether ester)s, PDN1(1-x)E1(x) and PDN1(1-x)E2(x) (x = 0%, 10%, 20%, 30%, 40%, 50%), were prepared in the melt with 1,10-decanediol as a comonomer. The synthesized poly(ether ester) s have weight-average molecular weights (M-w) in the range of 20,400-37,200 g mol(-1), and dispersity (D) values between 1.7 and 1.9. Thermal gravimetric analysis (TGA) reveal that all the poly(ether ester) s exhibit a two-step degradation mechanism with an initial degradation temperature above 350 degrees C. Results from differential scanning calorimetric (DSC) and wide-angle X-ray diffraction (WXRD) analyses demonstrate that the poly(ether ester) s are all semicrystalline materials with glass transition temperature (T-g) values ranging between -21.3 and -8.3 degrees C. The insertions of phenoxy-ether linkage and eugenol-derived composition have significant influence on the T-g, crystallinity, Young's modulus, and tensile strength, as well as the toughening effect and degradability.
