  • Figure 1. Intrinsic Viscosity Plot of ηred and ηinh vs Concentration for PVAc GB-50 in THF is shown. Extrapolation of the Huggins (ηred) and the Kraemer (ηinh) lines gives the intrinsic viscosity for the polymer
  • Figure 2. Plot of [η] vs solubility parameter (δ) for GB-11, GB-30, GB-50, and GB-75 are shown. The peak in each plot corresponds to the maximum intrinsic viscosity in THF
  • Figure 3. A double log plot of [η] vs Mw is shown. The slope is equal to the α and the intercept is equal to K, constants of the Mark Houwink equation
