is the most commonly used solvent for the synthesis of cross-linked polymeric microspheres by precipitation polymerization.Here
the innoxious acetic acid has for the first time replaced acetonitrile as a solvent in the precipitation polymerization of narrow disperse crosslinked poly(divinylbenzene)(PDVB-55)microspheres.Scanning electron microscopy(SEM)results showed that the PDVB-55 particles were uniform and well separated
and the diameter was measured to be 2.69 μm.X-ray photoelectron spectroscopy(XPS)shows that there are significant amount of double bonds on the surface of the microspheres.
