Abstract
Styrene (St)-N-acryloyl pyrrolidine (APr) copolymer latices were prepared by soap-free emulsion copolymerizations and the morphology of the latex particles was investigated. The shape of particles significantly depended on the polymerization conditions and reflected their inner structures which were examined by the electron microscopy of OsO4-stained and thinly sectioned particles. The wide variation of inner structures from a mostly uniform one to an extremely phase-separated one arose from differences in the copolymerization modes of the two monomers and the diffusibility of propagating chains in growing particles depending on polymerization conditions.
