Synthesis and Characterization of Highly Cross-Linked, Monodisperse Core−Shell and Inverted Core−Shell Colloidal Particles. Polystyrene/Poly(tert-butyl Acrylate) Core−Shell and Inverse Core−Shell Particles

摘要: We report on the synthesis of nearly monodisperse phase-separated polymer latexes with a well-defined core−shell morphology. Styrene/diisopropenylbenzene and tert-butyl acrylate/ethylene glylcol-diacrylate were used for either core or shell composite microgel particles. A major concern paper is detailed characterization inverse particles by static dynamic light scattering, transmission electron microscopy, solid-state NMR, analytical ultracentrifuge. The effect cross-linking agent final morphology discussed compared theoretical predictions.
