摘要：

The rheological properties of the water-salt solutions of polycationites were studied using acrylamide-sodium acrylate copolymers produced through the alkaline hydrolysis of the polyacrylonitrile fiber. Electrostatic interactions between likely charged copolymer segments ensure a low efficiency of the junctions of the entanglement fluctuation network, thus providing relatively low dynamic viscosity of solutions and the activation energy of viscous flow, as well as the absence of anomalies in the viscosities of concentrated solution. A change in the conditions of the alkaline hydrolysis of the polyacrylonitrile fiber (the alkali concentration and the chemical nature of an acid used for neutralization) has little effect on the rheological properties of water-salt solutions.
