Abstract
Styrene-acrylic emulsion with core-shell structure has been prepared by use of preemulsion and seed emulsion polymerization technology. The influence of initiators, emulsifier, monomer and temperature on the preparation of emulsion are discussed. The optimum conditions were : m(initiators)∶m(total monomers)=0.4∶100.0, m(emulsifiers)∶m(total monomers)=2.2∶100.0, m(styrene)∶m(butyl acrylate)=1∶1 and the reaction temperature controling at 80~82℃.
