The styrene-acrylic latex with core-shell structure was synthesized by semi-continuous emulsion polymerization. The effects of glass transition temperature（Tg），amount of acrylic acid in the core，amount and types of hydrophilic monomer on the freeze-thaw stabilityof the latex were investigated. When the Tg was about 20.94 ℃ and the amount of AA in the core was 2.5%，the freeze-thaw stability of the styrene-acrylic latex was better. The differenthydrophilic monomers and dosage presented little effect on the freeze-thaw stability，which al. so indicated that AA provided sufficient freeze-thaw stability to the latex system.
