摘要：

The gelation of a polymer gel formulated at 40 degrees C with 7500mg/L of partly hydrolyzed polyacrylamide (HPAm) and 3000 mg/L of Cr(III) acetate 50% active was monitored for 72h using H-1 nuclear magnetic resonance (NMR) techniques, oscillatory rheology, bottle testing, and UV spectrophotometry.
