In eq (1) and eq (2), [η], η sp , and η rel are the intrinsic, specific, and relative viscosities of the sample, respectively; k h and k k are the fitting parameters for the Huggins and Kraemer equations, respectively; C is the concentration of the sample. Fits calculated using these two equations were extrapolated to zero concentration to determine the intrinsic viscosity (see Figure for representative fits). Additional viscosity data can be provided upon request.
