Abstract

Monodisperse poly(styrene-co-acrylonitrile) microspheres were prepared by dispersion copolymerization of styrene (St) and acrylonitrile (AN) in ethanol (EtOH)/isopropanol medium. 2,2′-Azobis(isobutyronitrile) (AIBN) and poly(acrylic acid) (PAA) were utilized as initiator and steric stabilizer, respectively. The effects of PAA stabilizer, AIBN initiator, St/AN monomer ratio, and EtOH solvent on particle size and size distribution were investigated systematically. AN is a co-monomer with desired nitrile group (–CN); the functional P(St-co-acrylamidoxime) microsphere with chelating amidoxime group (–C(NH2)=NOH) was derived by amidoximizing the nitrile group with hydroxylamine. The percentage of chemical modification was calculated to be 51.2% in this study.
