On the photostability of some blue-emitting derivatives of 2-aminoterephthalic acid and their copolymers with methyl methacrylate

The photostability of eight blue-emitting derivatives of 2-aminoterephthalic acid, three of them containing a stabilizer residue in their molecule in dimethylformamide was investigated. Copolymerisation of methyl methacrylate with four of them, monomer compounds and whitening of methyl methacrylate “in mass” with one of the compounds was accomplished. The copolymers obtained have an intense stable to solvents fluorescence. Photostability of the compounds, thus included in the polymer chain increased. The influence of the luminophores on the photostability of the inherently and whitened “in mass” polymers was established.
