The pH inside a swollen polyelectrolyte network is calculated through a simple model, based on Donnan equilibrium and balance of mobile ions, extended to include the presence of a supporting electrolyte (salt) in the solution that swells the particle

Poly(N-vinylimidazole) hydrogels immersed in aqueous acid solutions produce an increment in the pH of the bath because of proton uptake by basic imidazole moieties, leading to hydrogel protonation. Both kinetic and equilibrium measurements of the pH

The swelling capacity (S) of poly(N-vinylimidazole) (PVI) hydrogels in aqueous acid solutions was measured as a function of the pH, the nature of the acid, and the polymer network structure. In acid solutions, imidazole groups become protonated and t

Fluorescence spectra of atactic and isolaclic poly-2-vinylquinoline and copolymers of 2-vinylquinoline and four non fluorescent comonomers have been measured as a function of pH. The homopolymers and the copolymers with pyrrolidone show two band fluo

The pH inside a dissolved polyelectrolyte coil or a swollen ionic polymer network is not accessible to direct measurement. It is here calculated through a simple model, based on Donnan equilibrium, counterion condensation (for charge density exceedin

The number of variables controlling the behavior of ionic gels is large and very often some of them are unknown. The aim of this work is to interpret quantitatively the swelling behavior of pH sensitive gels, with the minimum number of simplifying as

Measurements of preferential adsorption, λ(ν), by differential refractometry, and of swelling equilibrium, ν3−, of polydimethylsiloxane (PDMS) networks were carried out in the solvent mixture ethyl methyl ketone (MEK) + cyclohexane (Ch), at 25°
