The interlayer structural changes and the effects of modified MMT on the properties of poly-n-butyl succinate (Poly (butylenes succinate), PBS) were investigated. First of all, the modified MMT was obtained by cation exchange of sodium ions (Na+) in the interlayer of MMT and then PBS / MMT nanocomposites was prepared by solvent intercatation method. The wide-angle X-ray diffraction analyzer (WAXD) was used to analyze the interlayer distance of organic montmorillonite nanocomposites. Composting method was used to analyze the biodegradibility, and compared with the enzyme decomposition method. It is found that particle size and crystallinity will affect the decomposition rate of PBS. As the MMT content increased, the relatively smaller particles, will accelerate the hydrolysis reaction, and there by enhane the rate of biological decomposition.
