Paper Title:
Modified Hydroxyl Value Assay and Application in Analysis of Molecular Ingredient of Polylactic Acid Oligomers
  Abstract

A modification was proposed to overcome problems of inaccuracy while traditional end group analysis was applied for hydroxyl value assay of polylactic acid oligomer owing to hydrolyzation. The modified method possessed simplification and accuracy resulting from avoiding hydrolyzation of polylactic acid oligomers, and it could be used for characterising molecular ingredient of polylactic acid oligomers, while the other techniques, such as 1H-NMR, Fourier transform infrared spectroscopy and viscosimetry, were applied at the same time.
