-- The transition of the macromolccule of an acrylonitrile copolymer into the uncoiled state in lengthwise flow of aqueous salt solutions at concentrations from 1 · 10−3 to 5 · 10−2 g/cm3 has been studied.

-- The critical velocity gradients at which the tangled state of the macromolecules becomes unstable in a lengthwise field have been determined. It has been shown that the values of these agree well with predictions of the theory of semidilute polymer solutions.
