Abstract
Three species of pendant-type imidazolinium organosilicon copolymers were synthesized by β-(N-ethyl-2-imidazolinium bromide)ethyl methyl diethoxy silane with dimethyl silandiol and diphenyl silandiol, respectively, and by β-(N-benzyl-2-imidazolinium chloride)ethyl methyl diethoxy silane with dimethyl silandiol. The polyelectrolyte complexes formed by each of them with poly(sodium acrylate) were studied. Measurements of conductometry and turbimetry showed that the formation of polyelectrolyte complexes was governed by the structure of polycations, polyions concentration, ionic strength, solvent, and pH. It was found that the formation of polyelectrolyte complexes decreased with increasing rigidity of the polymer chain, ionic strength, and the quantity of organic solvent but with decreasing dielectric constant of the solvent.
