The preparation of monodisperse colloidal microlatex particles of polystyrene and poly(styrene butene diacid) by the use of microwave radiation and under normal ambient pressure is reported. There is no surfactant in the system.The total synthesis time has been reduced from more then 10h(conventional method) to less than 1 h(microwave mothod). The dynamic experimental results indicate that the reaction proecss is very sharp in comparison with conventional polymerization. No constant rate stage existed.
