FORMATION OF POLYELECTROLYTE COMPLEXES BASED ON PENDANT-TYPE IMIDAZOLINIUM ORGANOSILICON POLYMER WITH POLY(SODIUM ACRYLATE)

Three species of pendant-type imidazolinium organosilicon copolymers w ere synthesized by beta-(N-ethyl-2-imidazolinium bromide)ethyl methyl diethoxy silane with dimethyl silandiol and diphenyl silandiol, respec tively, and by beta-(N-benzyl-2-imidazolinium chloride)ethyl methyl di ethoxy silane with dimethyl silandiol. The polyelectrolyte complexes f ormed by each of them with poly(sodium acrylate) were studied. Measure ments of conductometry and turbimetry showed that the formation of pol yelectrolyte complexes was governed by the structure of polycations, p olyions concentration, ionic strength, solvent, and pH. It was found t hat the formation of polyelectrolyte complexes decreased with increasi ng rigidity of the polymer chain, ionic strength, and the quantity of organic solvent but with decreasing dielectric constant of the solvent .
