Two new water soluble dendronized polymers (PLn) from acrylate Behera amine monomer
of different molecular weights were successfully synthesized. The polymers were
characterized by FTIR, NMR, GPC and DLS. Both GPC and DLS results indicated that
these PLn have a remarkable tendency to form aggregates in solution that lead to apparent
molecular weights that are much higher than their theoretical values, as well as large
diameters in solution. However, the addition of any PLn to water did not cause any
increase in viscosity up to concentrations of 1000 ppm.
The possible interactions of PLn with the cationic surfactant CTAT were explored by
solution rheometry. A synergistic viscosity enhancement was found by adding small
