Abstrakt: 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 CaCl 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. [ABSTRACT FROM AUTHOR]
