Abstract： Poly(lactic acid)/epoxy furan resin/poly (butylene succinate) (PLA/FER/PBS) blends with different epoxy furan resin (FER) content were prepared by melt blending, while the effect of FER content on the dynamic rheological behavior and compatibility of the PLA/PBS blends was investigated by means of rotary rheometer, scanning electron microscopy (SEM) and universal testing machine. Results show that when the strain (γ) is less than 10%, the dynamic modulus does not change with the change of γ and the blends show linear viscoelastic behavior; when γ is more than 10%, the dynamic modulus decrease obviously, showing the "Payne" effect; FER can improve the processing properties of PLA/PBS blends;PLA/PBS blends have two different relaxation processes, the relevant curves have two distinct half arc, PLA and PBS phase morphology changed with the addition of FER; the time- and temperature-superposition-curves show that for PLA/PBS blends with FER content of 0.3 phr, of which, the Han-curves and vGP-curves of the blends present good overlap, implying the compatibility between PLA and PBS is good; the interface adhesion between PLA and PBS is the best, and the PLA and PBS has the most ideal interfacial compatibility; the tensile strength and impact strength of the blends reached the maximum value of 56.9 MPa and 4.33 kJ/m2, which is 11.2% and 37% higher than that of the simple PLA/PBS blends, respectively.
