• W4237472627 abstract "Quaternized, crosslinked, insoluble polymers of unsubstituted and substituted vinyl pyridines and a dihalo organic compound are spontaneously formed at ambient temperature on mixing the two components in bulk, in solutions or in suspension. The amount of crosslinking may be varied according to the composition and reaction conditions. The polymer product exhibits a high ion exchange capacity and undergoes a reversible color change from black at a pH above 7 to yellow at a pH below 7. The polymer may be formed in the presence of preformed polymers, substrates such as porous or impervious particles or films to deposit an ion exchange resin in situ or on the surface of the substrate. The coated or resin impregnated substrate may be utilized for separation of anionic species from aqueous solution. Porous walled hollow fibers prepared from polyacrylonitrile were used as scaffolds in which 4-vinyl pyridine dibromoethane ion exchange polymers were formed. The initial fiber hydraulic permeabilities of 6 x 10-5 cmjs atm were reduced to one fourth this value as the result of ion exchange resin formation in the pores of the walls. A concomitant decrease in permeability of non-electrolytes was observed, but very high rates of ion fluxes were noted when the fibers were used to separate ionic solutions. The Donnan pumping principle was demonstrated using strong Cl- concentrations to pump CrO4 = against its concentration gradient. The thin fiber walls led to high transport rates, and the apparently high degree of semipermeability permitted an adequate driving potential to be maintained. The need for a better theory of transport properties for ion exchange fibers is shown to be necessary. Several processes are operative simultaneously: the Donnan pumping process operates with constantly changing potential differences, and at the same time purely dialytic flows occur as the result of membrane imperfections. These flows are related through common concentration terms. The hollow fiber configuration allows the preparation of thin walled ion exchange devices with large surface areas; a recent cost calculation indicates such devices may make continuous water softening process costs (using the Donnan principle) economically competitive with present treatment methods." @default.
