Abstract

The formation of polyelectrolyte complex particles, at a nanometer level, by the complexation between poly(diallyldimethyammonium chloride) and two ionic/nonionic random copolymers of sodium 2-acrylamido-2- methylpropanesulfonate with either t-butyl acrylamide, P(AMPS54-co-TBA46), or methyl methacrylate, P(AMPS52-co-MM48), is described in this study. Dynamic light scattering and atomic force microscopy were used to investigate the influence of the polyanion structure, molar mixing ratio and titrant addition rate on the shape, sizes and polydispersity of the complex nanoparticles..

Keywords
