The work aims to explore the effect of polymerization conditions on the properties of alkali soluble acrylate emulsion to expand the application field of acrylate emulsion. The alkali soluble acrylate emulsion was synthesized by seed emulsion polymerization. The effects of solid content, polymerization temperature and pH value of reaction system on the properties of alkali soluble acrylate emulsion were studied by single-factor method. The structure and properties of the emulsion were characterized by Fourier transform infrared spectroscopy (FT-IR), high performance liquid chromatography (HPLC)and thermogravimetric analysis-differential scanning calorimetry (TG-DSC). According to the results, the alkali soluble acrylate emulsion with a viscosity of 10-14 mPa.s could be synthesized by controlling the polymerization conditions and setting the polymerization temperature at 75 ℃. The acrylate emulsion has good application prospects in packaging adhesives and functional membranes.
