Production of anomalous particles in the process of emulsifier‐free emulsion copolymerization of styrene and 2‐hydroxyethyl methacrylate

Abstract
It was found that copolymer particles produced by emulsifier‐free emulsion copolymerization of styrene and 2‐hydroxyethyl methacrylate had an anomalous shape with uneven surface. The formation mechanism is discussed.
