Evaluation of unperturbed and thermodynamic parameters of polymer solutions from viscometric data

The existing approximate theories of polymer solutions are generalized by a simple equation. It is combined with the Kirkwood- Riseman perturbation treatment of viscosity together with the Kuhn model of random coil dimensions to produce two expressions for the unperturbed and thermodynamic parameters of polymers in solvents. A test of these equations on a large variety of polymer systems yields results which are comparable with the experimental values.
