New core-shell acrylic latexes designed for crosslinking with cycloaliphatic diepoxides were prepared. The core consisted of methyl methacrylate (MMA), butyl acrylate (BA), 2-hydroxyethyl methacrylate (HEMA), and the shell MMA, BA, and methacrylic acid (MAA). A strong acid acrylate was incorporated into the shell to catalyze the crosslinking reactions. The diepoxide was embedded in core of the latex, which contained the less reactive functional monomer HEMA. The pot-life stability of epoxide was shown to be dependent on latex morphology, initiator system, and reaction conditions. The latexes were crosslinked with cycloaliphatic diepoxide added as an emulsion or as solution (organic solvent).
