Abstract：To solve the problemsof migration，precipitationand por antibacterial efectof antibacterial agentadded to poly-arylic resin，aquaternaryphosphonium salt antibacterial monomer—methacryloyloxypropyl triphenylphosphonium bromide（Br-MAP）was synthesized and used to synthesize quaternary phosphonium salt containing polyacrylic emulsion.The quaternary phosphonium salt monomer and poly-acrylic emulsion were respectively characterizedby 1H -NMR and ATR-FTIR.Efects of antibacterial monomer contents on the emulsion polymerization stability andthethermal stability，film propertiesand antibacterial properties of poly-acrylic emulsion resincontainingquaternary phosphoniumsalt were evaluated byTGA，filmproperty test andagar platedifusionmethod.Theresults showthat with the increase of the content of Br-MAP，the polymerization stabilityof emulsion is improved，the particle size of emulsion becomes smaller，whilethe water absorptionoffilmincreases and the thermal stabilitydecreases. When the content of Br-MAP respectively is 2% and 6% ，the antibacterial rate against Staphylococcus and Escherichia coli reachs 99.99%
