Synthesis of polystyrene in alkyl glucoside microemulsion

Small particle size (46.6 nm) and monodisperse (P=0.1060.2) polystyrene particles was prepared using K_2S_2O_8 as initiator in the O/W microemulsion of H_2O-APG0810-ST. The influence of APG0810 concentration,initiator concentration and salt concentration on particle size and polydispersity of polystyrene has been discussed. The result is that the particle size become small (44.3 nm) with the APG0810 concentration increasing, and the monodispersity become weak; while with the salt concentration increasing the particle size become small(45.2 nm) , but when salt concentration is more than a certain concentration, the particle size has a tendency to big. The particle size become small(41.2 nm) with initiator concentration increasing.
