摘要
Covalently-colored polymer latex was synthesized via batch emulsion copolymerization of styrene, butyl acry- late and methacrylic acid in the presence of red polymerizable dye monomer consisting of anthraquinone chromo- phore, alkyl spacer and acryloyl group, and the influences of the initiator, surfactant and polymerizable dye on the polymerization and the latex properties were investigated. Results showed that the initiator amount was a determi- native factor for the monomer conversion, and a high conversion of the polymerizable dye could be achieved when the ammonium persulfate amount was equal to or more than 1 wt% to the total monomers. Most of the chromo- phores were covalently bonded to the polymer chains if the polymerizable dye was used in the range of 0-1.5 wt% The light fastness of the resulting latex fihn was much better than that of the noncovalently-colored polymer film.
