摘要：
The influence of swelling time,temperature,NaCl concentration and polymer micro-gel concentration on rheological properties of polymer micro-gel dispersions was studied by using a HAAKE rheometer.The results showed that with increasing swelling time and NaCl concentration,the polymer micro-gel dispersions changed from a shear-thickening fluid to a Newtonian fluid.The polymer micro- gel dispersion show shear-thinning in non-saline water.At higher swelling temperature,the time of the polymer micro-gel dispersion showing shear-thickening was shorter.With increasing polymer micro-gel concentration,the dispersion changed from shear-thickening to shear-thinning.
