Objectives

  1. Prepare four dilute solutions from the stock solution of PVOH (MW 130,000), diluting by 0.75, 0.5, 0.25 and 0.125
  2. Measure the viscosity of PVOH (MW 130,000) at the concentrated stock solution and the four diluted concentrations
  3. Make PVOH (MW 22,000) films in H2O with 2-20wt% maleic or succinic acid and HCL or H3PO3


PVOH (MW 22,000) Films

  • The following were prepared using the General Protocol for film preparation described on 08/29/12
