A kind of functional polymeric microspheres with weak anion exchange group of diethylaminoethyl (-DEAE) with particle diameter mere than 5 micrometers, as well as narrow dispersion in diameter, has been synthesized with moncmers of diethylaminoethyl methacrylate (DEAE-MA), vinyl acetate (VAC) and divinylbenzene (DVB) initiated by 2,2'-azo-isobutyronitrile (AIBN) at 65℃ for 10hr. The effects of reaction condition, such as components ratio of the reaction system, polymerization temperature and time on the diameter and distribution of particle diameter have been studied.
