Study of the effect of polyion charge density on structural properties of complexes between poly(acrylic acid) and Alkylpyridinium surfactants

Article Abstract:

Synchrotron X-ray scattering was used to investigate the structural properties of complexes of poly(acrylate) anion (PA) and the cationic surfactants dodecylpyridinium (DPC) and cetylpyridinium chloride (CPC) at various degrees of neutralization of alfa(sub N) of poly(acrylic acid) (HPA) and at a fixed surfactant:polymer molar ratio. It was demonstrated that the ionization degree of COOH groups of the polymer increases upon surfactant binding.

Monte Carlo simulations of polyion-macroion complexes. 2. Polyion length and charge density dependence

Article Abstract:

Monte Carlo simulations were used to study the complexation between a polyion and an oppositely charged spherical macroion in the framework of the primitive model. It was observed that as the chain stiffness is increased, a transition from the one-tail state to a two-tail state appeared for long and highly charged polyions.
