Applications of Infrared Spectrometry in Molecular Groups Analysis of Plasticized Starch

Abstract:

In order to study the recrystallization of the thermoplastic starch, this paper obtained the IR spectra of starch respectively plasticized by urea, glycerin and glycol. By analytical solutions spectra of vibration frequency of molecular groups, the paper studied the destructive effect of starch crystal structure, and plasticizer to form new hydrogen bonds with starch by hydroxyl group bonded. Excessive plasticizer was not suggested. When the ratio of starch and urea was 102, the thermoplastic starch was excellent in thermoplasticity and hot-workability.
