Emulsionfier-free Emusion Copolymerization of MMA/BA

The MMA/BA copolymer emulsion was prerared by emulsionfier-free emulsion polymerization using methyl methacrylate(MMA) and butyl acrylate(BA) as comonomers,APS as initiator.The result showed that the MMA/BA copolymer emulsionfier-free emusion has best stability when the mass ration of MMA:BA was 1:1 and mass fraction of the initiator was 0.24%.The monomer conversion ratio was 81.84% with the condition of the temperature 80℃ and the reaction time 8h.
