Abstract: With sodium persulfate as initiator,methyl methacrylate（MMA）,vinyl versatate（VeoVa10） and butyl acrylate（BA） as modified copolymer of vinyl acetate（VAc）,a modified polyvinyl acetate（PVAc） emulsion was prepared by pre-emulsifying before semi-continuous dripping.The influences of some factors such as mix round speeds,comonomers proportion,polyvinyl alcohol（PVA） and initiator contents were discussed on modified PVAc emulsion properties.The results showed that the modified PVAc emulsion had better c... More
