Reduction of the hydrodynamic resistance to turbulent water flow with copolymers of acrylamide, acrylonitrile, and 2-acrylamido-2-methylpropanesulfonic acid

详细

The influence of the ratio of acrylamide, acrylonitrile, and 2-acrylamido-2-methylpropanesulfonic acid monomeric units in the terpolymer on its molecular-mass characteristics was studied. The influence of the copolymer composition on its resistance to the action of CaCl₂ was determined. The capability of the synthesized terpolymers to reduce the hydrodynamic resistance to a liquid flow was evaluated with a laboratory capillary turbulent rheometer. The hydrodynamic resistance reduction effect depends on the molecular-mass characteristics of the terpolymers.
