Abstract: The factors that influence the latex particle size and water absorptionof styrene-acrylic emul-sion was investigated,which includes the varieties of surfactant. sorts and ratio of initiators. functional monomers, solid content and ratio of monomers for seed emulsion polymerization. Some laws were concluded from the experiments, which was discussed briefly.

Key words: styrene-acrylic emulsion;latex particle size, water absorption of film
