Electrostimulated shift of the precipitation temperature of aqueous polyzwitterionic solutions

The precipitation temperature (T-pr) value of aqueous poly(dimethylaminoethoxyacryloyl-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.
