| Abstract: | Seed latex with narrow particle size distribution was first prepared by emulsion polymerization with styrene and butyl acrylate as monomers and varying amounts of emulsifiers and initiators,which was then used to achieve stable core/shell latex with second stage monomers consisting of methyl methacrylate,ethyl acrylate and methacrylic acid(MAA),by batch and semi-continuous emulsion polymerization.Particles size and morphology of the latexes prepared by the two processes were compared.The effects of methacry... |
