| Abstract: | Partially hydrolyzed polyacrylamide (HPAM) is modified by pan-milling. HPAM samples of different milling cycles are obtained. The relationships are studied between intrinsic viscosity and apparent viscosity of the aqueous solution of each sample and the number of milling cycles, and the effects of shear rate and aging time on the apparent viscosity are also discussed. It is shown that (1) the intrinsicviscosity and the apparent viscosity of the aqueous solution of every sample decrease as the number of milling cycles increasing; (2) the apparent viscosity decreases with the increase of shear rate when millingcycle number is less, and it increases slightly when milling cycle number is greater, (3) the apparent viscosity of every sample solution decreases with the increase of the aging time after milling. |
