    Abstract
    Chemical cross-linking was developed to prepare starch and chitosan-based hydrogels. First, the precursor of starch was synthesized through the reaction of carboxymethylation with sodium monochloroacetate, and then chitosan was grafed by using methacrylic acid as cross-linker. In this research, sago and cassava starches were used and mixed with chitosan, and the efect of methacrylic acid concentration was investigated to determine the grafing parameters and hydrogel characteristics. Compared to native starch and carboxymethylated starch, hydrogels from both starches have high ability to swell and high capacity to absorb water and oil. Te highest grafing yield, grafing efciency, and monomer conversion were achieved by experiment using 0.550 g of methacrylic acid per g of CMS-chitosan mixture. Tese hydrogels have a good potency as biodegradable absorbents for pharmaceutical and industrial application.
