KINETICS OF REACTIONS BETWEEN OPPOSITELY CHARGED LINEAR AND NETWORK POLYELECTROLYTES

The kinetics of the reaction between oppositely charged linear and net work polyelectrolytes was studied. The rate of transfer of the linear polyions in an oppositely charged gel is determined by the rate of int erpolyelectrolyte exchange reactions within a polycomplex layer. The s orption of a linear polyelectrolyte grows upon increasing the ionic st rength of the solution and decreasing a degree of polyion dissociation . The transfer rate of the linear polyelectrolyte depends also on the molecular characteristics of the penetrant.
