| Research Abstract |
Styrene microemulsion with some azo-initiators were irradiated by UV-liht for a certain time, and after a certain period the particle size distribution of the obtained polymer particles was measured by transmission electron microscopy. The irradiation period, polymerization period and reaction temperature were valied. The polymer particles with the average diameter being c.a. 21 nm and with relatively-sharp size distribution were obtained at proper conditions, but monomeric conversion was low. The polymer particles with the average diameter being c.a. 26 nm and with relatively-sharp size distribution and with monomeric conversion being over 80% were obtained by polymerizing during phase-inversion emulsification with p-methyl styrene and a kind of nonionic surfactant.
