Abstract: Molecularly imprinting polymer microspheres for 4-aminopyridine were prepared by means of an emulsifier-free seed emulsion polymerization from ethyl acrylate and styrene using octanol and a very small amount of OS as the dispersive reagent. When the octanol and OS were employed at certain ratios, a small size and uniform distribution of the microspheres were observed. The optimal condition was found, i.e. , the dosage of octanol was 3.0 wt %, weight ratio of ethyl acrylate/styrene was 1 : 0. 229, pH was 8.0, and the polymerization temperature was 85 °C.
