DEGRADATION OF POLYMER SOLUTIONS IN A HYDRODYNAMIC FIELD WITH A LONGITUDINAL VELOCITY GRADIENT

A fl ow diagram of degradation of polymer solutions under the action of a hydrodynamic fi eld with a longitudinal velocity gradient has been established. Intra- and intermolecular branchings (cross-linkings) that dominate over the rupture of macromolecular chains are initiated by the hydrodynamic fi eld.
