摘要：

Monodisperse microgels were prepared by the precipitation polymerization of acrylamide with acryloyl-terminated-poly(ethylene glycol) (PEG) macromonomer as a stabilizer. The process was carried in ethanol, methanol, and a mixture of two. The size of microgels was controlled to the range of 0.06-1.0 mu m, changing the solvent. GPC profiles and particle size distribution of the microgels were narrow and monodisperse. Microgels were dispersable in water, and showed very low viscosity, and were stable in polar solvents and KCl aqueous solution.
