This articles is comprised of two parts: a) an experimental investigation on the behavior of an acrylic gel under DC electric field and b) a physico - mathematical description.a) Gel rods made of poly [acrylamide-co-bisacrylamide] were partially hydrolyzed to different extents at pH 12 by teteramethylethylene diamine. Equlibrium properties of the resulting gels rods (water content,...

The equilibrium properties of ionic microgels are investigated using a combination of the Poisson-Boltzmann and Flory theories. Swelling behavior, density profiles, and effective charges are all calculated in a self-consistent way. Special attention is given to the effects of salinity on these quantities. In accordance with the traditional ideal Donnan equilibrium theory, it is found that the e...

A random mixture of bifunctional and tetrafunctional units is placed on a simple cubic lattice. Permanent bonds between these units are then formed by the random motion of active centres (radicals) resulting in a model for the gelation of polyacrylamide and similar processes. The largest of the clusters formed by this kinetic percolation process is identified with the gel fraction, the ‘mean cl...

Excess molar enthalpies, E H of 1-methyl pyrrolidin-2-one or pyrrolidin-2-one or benzene (i) + oor mor p-chlorotoluene (j) binary mixtures have been measured over entire composition range at 298.15 K using high sensitivity differential scanning calorimeter Micro DSC (Model – μDSC 7 Evo). The E H data have been fitted to Redlich-Kister equation to estimate binary fitting parameters and standard ...
