Lz. Rogovina et al., ACID-BASE AND RHEOLOGIC PROPERTIES OF SOL UTIONS OF POLYACRYLAMIDES WITH DIFFERENT DEGREES OF HYDROLYSIS, Vysokomolekularnye soedinenia. Seria A, 35(1), 1993, pp. 10000078-10000082
Acid-base properties of water solutions of polyacrylamide and hydrolyz
ed polyacrylamides with different degrees of hydrolysis were studied b
y method of pH-metric titration. The acid-base equilibrium constants o
f polyacrylamide solutions were determined. Based on the acid-base pro
perties determined, we attempt to explain the changes in the rheologic
al properties of the polymers, which occur over time and in a wide ran
ge of pH values.
