in this study, alkali soluble resins(ASR) were prepared from EA(Ethyl acrylate), MAA(Methacrylic acid), MMA(Methylmethacrylate), SM(Styrene monomer) and UAN(Urethane acrylate nonionomer) by emulsion polymerization. The effects of polymerization condition, such as emulsifier types and contents, initiator contents and neutralizing agent types, on the physical properties of ASR were investigated. Thermal properties were investigated by differential scanning calorimeter(DSC) and thermo gravimetric analysis(TGA). |
