Lignin is a cheap material available abundantly in nature, and as one of the means to increase its practical applications, blending the lignin with polymers has been studied. In order to obtain the polymer/lignin blends having desirable performance properties, proper compatibility between the lignin and matrix polymer is required. In this study, alkali lignin was chemically modified to have long alkyl groups, and the alkylated lignin was incorporated into poly(butylene succinate) (PBS), one of the important biodegradable aliphatic polyester, by a melt blending. Morphology, thermal, and mechanical properties of the PBS/alkylated lignin blends were characterized by SEM, DSC, DMA, and tensile testing. |
