Synthesis of poly(acrylamide‐<i>co</i>‐divinylbenzene) microspheres by precipitation polymerization

Abstract

Highly crosslinked poly(acrylamide-co-divinylbenzene) microspheres have been prepared by precipitation polymerization in the presence of an acetonitrile medium. The divinylbenzene concentration plays a pivotal role in not only the formation of individually stable microspheres but also the polymerization characteristics, including the final size, uniformity of the particle size, yield of the polymerization, and thermal properties.
