Emulsion Polymerization The polymerization of 4acetoxystyrene in emulsion using 1 as a CTA and potassium persulfate as the initiator in the RAFT process at 708C led to a stable latex of poly(4acetoxystyrene) (M—. n = 5550 g/mol and PDI = ) with 70% conversion in 12 h.
Emulsion polymerization can occur using a batch process, semicontinuous process or continuous process. Commercial latex polymers are made using a semicontinuous or continuous process rather than a simple batch process because the heat evolved in a simple emulsion batch process would be uncontrollable in a large reaction vessel.
Emulsion polymerization of styrene was performed radical initiator. The concentration of surfactant in the reaction at 70 1C in a batch reactor at a constant stirring rotation.
Synthesis of polystyrene nanoparticles with different surface modification by emulsion polymerization and measurement of IgG adsorption and stability for the application in latexprotein complex based solidphase immunoassay.
Microemulsion and emulsion polymerization can have some similarities in starting conditions and polymerization mechanism, but the resulting nanoemulsion .
