V. Kim et al., THE INTERPLAY BETWEEN HYDRODYNAMIC AND ST RUCTURAL CHARACTERISTICS INSURFACTANT POLYACRYLONITRILE SYSTEMS, Vysokomolekularnye soedinenia. Seria A, 36(1), 1994, pp. 110-114
The effects of inorganic electrolytes and different cationic surfactan
ts on hydrodynamic characteristics of polyacrylonitrile in DMF were st
udied. Using velocity sedimentation, it was demonstrated that the addi
tives cause contraction of the macromolecular coil. The correlation be
tween structural characteristics of the macromolecules in solution and
in die solid phase was established. This makes it possible to control
the viscoelastic properties and texture of polyacrylonitrile films by
using surfactants.
