Expanding the applications of poly(butylene succinate) (PBS) in processing fields requiring high melt strength, PBS/solid epoxy (SE)/carboxyl‐ended polyester (CP) blends with high melt viscosity were fabricated by the in‐situ crosslinking reaction using SE and CP. The influence of SE/CP had been studied in terms of the rheological property, crystallization behavior, and mechanical property of PBS. The results showed that the melt viscosity of PBS could be enhanced significantly by three orders of magnitude, when the loading ratio of SE to CP was over 15/15. Furthermore, it had also been found that SE/CP component had positive impact on the mechanical properties of PBS, inclusive of reduction of brittleness. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.
