| Abstract: | Highly monodispersed poly(methylstyrene) (PMS) latex particles were prepared by the emulsifier free emulsion polymerization using 2,2'-azobis-(2-amidineopropane) dihydrochloride (V-50) as an ionic initiator. The effect of initiator concentration, agitation speed, and ionic strength on the rate of polymerization and the particle size were studied. Furthermore, the similarity and difference between the emulsifier free emulsion polymerization of styrene and methylstyrene are compared.The results showed that under suitable conditions the monodispersed poly(methylstyrene) latex particles can still be synthesized by the emulsifier free emulsion polymerization. |
| Keywords: | emulsifier-free emulsion polymerization highly monodispersed latex particles poly(methylstyrene) |
