The Impact of Ion Exchange on Nature of Polyacrylic Acid and Nonionic Polymer Complex Formation

Abstract:

This paper provides substantiation for division of interpolymer complexes, that are stabilized by hydrogen bonds formed between polyacrylic acid and non-ionic polymer into strong-and low-complexing couples, and elucidates the nature of observed differneces. It is shown, that the formation of complex in presence of low molecular salt depends not only on the energy and number of hydrogen bonds, but on the degree of swelling of polyacid coil too. It is established, that the effect of low-molecular salt on the degree of swelling of the polyacid coil is not unambiguous. The size of the coil is increased by the salt adding at relatively low concentrations as a result of local ion exchange.
