ResumoThe copolymerization of methylmethacrylate (MMA) with 1,8-naphthalimide fluorescent brighteners (fluorophores) yielding transparent blue fluorescent side-group copolymers has been investigated. It has been found that more than 0.92% of the fluorophores are chemically bonded to the polymer chain. Changes occurring in the chromophoric systems of the fluorophores during copolymerization have not been detected. The effect of polymer modification has been proved by an appropriate spectrophotometric method. The influence of the studied monomeric 1,8-naphthalimide fluorescent brighteners upon the photostability of the structurally bleached polymethylmethacrylate has been determined.
