Objectives

  • Crosslink PVOH films through dehydration.
  • Prepare more PVOH (MW 130,000) films using HCl, H3<sub/>PO4,and maleic or succinnic acid
  • Run solubility tests of crosslinked and uncrosslinked PVOH films
  • Run Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning calorimetry(DSC) on PVOH films
