A new kind of blend material was prepared by the incorporation of lignosulfonate calcium (LS), as the filler, into biodegradable poly(butylene succinate) (PBS), as the polymeric matrix, with the process of melt mixing and subsequent compression molding. The nucleation of LS improved the crystalline properties of the PBS component in the blends. Combined with the rigidity nature of the LS filler, the Young’s modulus values of the blends were enhanced. Furthermore, the introduction of LS in this biodegradable polyester slightly increased the hydrophilicity of the blends, shown as higher values of water uptake at equilibrium; this might facilitate the biodegradation of hydrophobic polyesters. Consequently, this study opened one way of enhancing the rigidity and decreasing the cost of biodegradable PBS-based polymeric plastics.
