Using butyl acrylate, styrene, hydroxylethyl methacrylate and acrylic acid as comonomers, emulsions containing high hydroxyl content and having core-shell structure were synthesized from semi-continuous seed emulsion polymerization methods. Emulsifier types and levels, reaction temperature, core composite, weight percent of core on stability of the emulsion polymerizations were investigated. It was found that when mixed emulsifiers SDS/OP were used, at a level of 1%, and a ratio of SDS/OP of 4/6, the polymerization process had lower coagulum. Compared with emulsion without core-shell structure, when the hydrophilic monomer was not used in core composite, coagulum had decreased greatly and the amount of emulsifier may be reduced.
