Abstract
Epoxy resin/acrylic composite latexes were prepared by miniemulsion polymerization. Epoxy resins have a functional epoxy group in them and excellent characteristics, such as heat resistance and good adhesion. Acrylic latexes have weather and water resistance. Combining the epoxy resin and the acrylic latex was an attempt to actualize these advantages. The miniemulsion polymerization method was effective in obtaining the composite latex. A less than 500βnm droplet size for the monomer preemulsion was necessary to obtain the latex in a stable manner. Dimethylaminoethylmethacrylate and methacrylic acid as the reactive functional monomer with an epoxy group were introduced to the latexes. The effect of the polymerization method of these functional groups on the properties of latexes and their films was investigated. The latex prepared by the twoβstage polymerization method had good polymerization stability, storage stability, and solvent resistance. Β© 2001 John Wiley & Sons, Inc.

An approach to prepare high solids content latexes ( ΓΊ50 wt %) is presented. The approach is based on a two-stage polymerization where in the first stage low-tomedium solids content seed latexes with a broad particle-size distribution (PSD) were prepared by semicontinuous miniemulsion polymerization
This article demonstrates the direct intercalation of an epoxy polymer in the interlayer of Na / -montmorillonite (MMT) by a step type of polymerization in an aqueous emulsion media. The synthesis and the results of structural and thermal characterizations for this hybrid composite are described. Eq
