Poly (ethylene 2,5-furandicarboxylate)(PEF)/poly (butylene succinate)(PBS) blends were obtained via melt blending,and the factors,such as the blending temperature,blending time,the screw speed and blending ratio on mechanical properties of PEF/PBS blends were studied in details.Their compatibility,thermal property,and mechanical property were investigated by scanning electron microscopy,differential scanning calorimetry,thermogravimetric analysis,and tensile testing and impact testing.When the content of PBS is 15%,the optimal blending processing conditions are mixing the blends at 230℃ for 90 s under the screw rotation speed of 150 r/min.Under the optimal conditions,the compatibility and thermal performance are good,the impact strength and tensile strength are the largest.Compared to PEF,the impact strength and the tensile strength of the blend increase 6 times and approximate 20%,respectively.The results in this work provide a new possibility for the application of biobased polymers.
