Degradation of Corn Starch with NaOH/urea and Synthesis of DS-G-AA Copolymers

Article Preview

Abstract:

Properties of corn starch dissolved in NaOH/urea aqueous solutions were studied in this research, and NaOH/urea at different ratios in aqueous system was used to treat corn starch (CS). NaOH/urea breaks down the structure of CS, resulting in chemical degradation. After degradation, the change of molecular weight was analyzed by GPC-MALLS. The degraded CS (DS) and native CS(NS) were grafted with acrylic acid and compared in FTIR and both DS and NS were successfully grafted with AA.
