摘　　要：Reverse atom transfer radical polymerization of styrene was conducted in emulsion by using Cu(II)/2,2′- bipydine or Cu(II)/phen complexes, AIBN or V50 as the ini- tiator, Brij-98 or OP-10 as the surfactant. The results of GPC showed that both polymerization processes exhibit living characters when using AIBN as the initiator. However, when V50 was used, the monomer conversion was fairly low and the whole polymerization was not controlled well. The meas- urement of particle size and its distribution told us that the latex particles were mean and stable when using Brij-98 as the surfactant.Reverse atom transfer radical polymerization of styrene was conducted in emulsion by using Cu（Ⅱ）/2,2＇bipydine or Cu（Ⅱ）/phen complexes, AIBN or V50 as the initiator, Brij-98 or OP-10 as the surfactant.
