抄録: | Electrophoretic behaviors of a synthetic polyelectrolyte, poly(vinyl alcohol) partially acetalized with glyoxylic acid (PVAG), were studied. The mobility was found to be almost independent of the degree of polymerization. The mobility-polymer concentration curve appears to have a minimum for materials of high charge density, whereas it is steadily decreasing for those of low charge density. Moreover the mobility variation with the ionic strength of buffer solution showed a tendency of decreasing under our experimental condition. The number of charges of this polyacid was estimated by means of Debye-Henry's relation from the observed (descending) mobility and found to be in a fairly good agreement with the value determined by conductomentric titration with an exception at the very low ionic strength. |
