The preparation method and the product properties of cross-linked esterified corn starch were studied by using terephthaloyl chloride as the crosslinking agent. Single factor experiment was used to optimize the preparation of terephthaloyl chloride cross-linked esterified starch, and the fourier transform infrared spectroscopy(FT-IR), scanning electron microscopy(SEM), X-ray diffraction(XRD) and brabender viscometer were used for the characterization of the prepared products. The physicochemical properties ...
