Poly[methyl methacrylate(MMA)-co-2-hydroxyethyl methacrylate(2-HEMA)] particles were synthesized by dispersion polymerization in a cyclic hydrocarbon medium. The reactions were carried out at 72~80℃ in the presence of SIS block copolymer and t-butyl peroxy-2-ethyl hexanoate, as steric stabilizer and initiator, respectively. The used cyclic hydrocarbon medium were cyclohexane and methyl cyclohexane. The resulting poly(MMA/2-HEMA) latexes were found to be monodisperse particle diameter of 2~3㎛. Dispersion polymerization of poly(MMA/2-HEMA) were carried out to investigate the effect of concentration of initiator. The molecular weight of poly(MMA/2-HEMA) in presence of methyl cyclohexane than cyclohexane was increased.
