Abstract
The polymerization kinetics and the morphology of PVC-seeded styrene emulsion polymerization were investigated. Batch polymerization technique was employed find transmission electron microscopies coupled with OSO4, RuO4-staining methods were used for the morphological studies. The rate of polymerization was found to be independent of the swelling time find the initiator concentration (K2S2O8), but it increased along with the agitation speed. The strong acidic condition of polymerization medium and the addition of isoprene, DVB or CHBr3 slowed down the rote of polymerization. The PVC-PS composite latexes had constant morphology regardless of the change in polymerization parameters. The "off-centered core-shell (PVC-core, PS-shell)" morphology was thought to be originated from the low swelling of PVC with styrene. Crosslinking agent mode the morphology "concentric core-shell" and a common solvent to PVC find PS made the smooth composite particles.
