The Mark-Houwink equation for the linear polymers in the GPC solvent relates intrinsic viscosity to the viscosity average molecular weight ([M.
The simplest method was the determination of the viscosity of the PVC solution, the result of which was then expressed in the form of viscosity-average molecular weight calculated from Mark-Houwink equation.
The solvent used for PEN was a 50/50 (v/v) mixture of phenol (>99%, Aldrich) and 1,2,4-trichlorobenzene (>99%, Aldrich); the viscosity measurements were made at 30[degrees]C, and the Mark-Houwink equation employed to calculate the number average molecular weight was derived from the data of Po et al.
