摘要: This paper deals with the behaviour of hydrolyse d Polyacrylamide solutions in presence chromium III. First, using potentiometry and spectroscopy, we study complexation between III sodium acetate used as a low molecular weight model for polymer. Then same methods are applied to investigate polymer—Cr(III) results discussed conjunction nature physical states systems. Finally, perform rheological measurements sol—gel transition regime range where number crosslinking points can be calculated unambiguously.
