The precipitation temperature (T pr ) value of aqueous poly(dimethylamino‐ethoxyacryloyl‐propylsulphonate) (PDMAPS) solutions decreases with the rise of electric field intensity both in the absence and in the presence of a low molecular salt. This electrostimulated T pr shift is explained qualitatively by means of the model taking into account both the dominating intermacromolecular dipole‐dipole interaction and the dipole cluster formation.
