The dispersant applied in this investigation is Acumer 9400 was supplied from The Dow Chemical Company, Midland, Michigan, USA. It is a water-soluble sodium salt polymer used to disperse and stabilize high-solids mineral slurries. It is anionic dispersant of sodium polyaciylate polymer (SPA) of solid content 41-43 wt% with a molecular weight of 3000-4000 g/mole. 

Counterion condensation theory (CCT) predicts the concentration of bound counterions (1-5). However, traditional experim tal methods only measure the fraction of counterions bound and not their concentration within e condensed volume. The chemical trapping method provides this information (7-11). Here, we use chemical trapping to estimate e concentration of counterions in the condensed volume of an anionic polyelectrolyte, sodium polyaciylate, NaPAA and compare our result with that obtained from CCT. 

Aqueous sodium polyaciylate solutions were prepared in 1 x 10 M HEPES buffer at pH 7. Solid l-ArN2BF4 was added to ch solution such that the ratio of polyelectrolyte to l-ArN2 was approximately 33 1, Solutions were placed in a 40 C constant temperature water bath for a minimum of ten half lives.

Rossi et al. [30] evaluated rheologically mucins of different origin with polyacrylic acid and sodium carboxymethyl cellulose. The same group also reported a novel rheological approach based on a stationary viscoelastic test (creep test) to describe the interaction between mucoadhesive polymers and mucins [31,32]. Jabbari et al. [33] used attenuated total-reflection infrared spectroscopy to investigate the ehain interpenetration of polyaciylic acid in the mucin interface.
