Viscometric determination of the two critical concentrations of polymers in solution

A viscometric study is presented using ternary systems polymer-1/polymer-2/solvent. The variation of the reduced viscosity of the polymer mixture with the total concentration shows two crossover points corresponding to the two critical concentrations of polymers C∗∗ and C∗. The influences of the tem...

Description
Summary:A viscometric study is presented using ternary systems polymer-1/polymer-2/solvent. The variation of the reduced viscosity of the polymer mixture with the total concentration shows two crossover points corresponding to the two critical concentrations of polymers C∗∗ and C∗. The influences of the temperature and of the hydrodynamic volume of the polymers on the critical concentrations are also presented.
