Polymerization of maleic anhydride and 2-vinylnaphthalene produces alternating polymers. Imidization of the polymer with amino-terminated polystyrene yields different loadings of an alternating polymer with polystyrene combs''. Upton rigorous hydrolysis one obtains poly(2-vinylnaphthalene-alt-maleic acid)-graft-polystyrene (P2VNMA-PS), which is a fluorescent polymer with unusual solution properties and with significant surface activity. P2VNMA-PS forms a small micelle structure in solution or can be used as a surfactant for an emulsion polymerization of polystyrene (no cosurfactant is required), producing monodisperse latex particles which are stable for pH > 3.9. Centrifugation shows that >90% of the P2VNMA-PS is associated with the latex particles. Fluorescence quenching studies of the naphthalene excimer with Tl[sup +] indicate that approximately 84% and 77% of the naphthalene groups remain exposed to the aqueous phase when this polymer is micellized or incorporated onto a latex particle, respectively. These data imply that the P2VNMA-PS polymer is permanently associated with the exterior of the latex particle, as one would expect given the amphiphilic nature of this polymer.
