| Abstract: | The acrylic ester and styrene core/shell emulsion copolymer has been prepared by using two-stage polymerization process. Factors affecting the copolymerization have been studied, such as kinds and amounts of emulsifier and initiator, ratio of the monomers, the feeding methods and the copolymerization temperature.It has been demonstrated that the latex had a structure with core/shell by using TEM and DSC. The stability of the latex has been examined by chemistry, machinery, freezing thaw and dilution. |
