INFLUENCE OF THE MOLECULAR PARAMETERS OF ANIONIC ACRYLAMIDE COPOLYMERS ON THE VALUE OF THE THOMS EFFECT IN DIRECT OIL EMULSIONS
S. V. Chichkanov, A. I. Shamsullin, and V. A. Myagchenkov (Mjagchenkov) UDC 532.529.5:678.745.842 The influence of molecular parameters (molecular weight and polydispersity in molecular weight) on the value of the reduced Thoms effect in 10% direct oil emulsions has been analyzed with the example of the specimens of anionic acrylamide copolymer of different molecular weight, which were obtained by the ultrasonic-destruction method. The prospects of anionic acrylamide copolymers for use as admixtures reducing the drag of turbulent oil-emulsion flows have been noted for the complex heterophase system studied.
