Abstract
New triazene urethane methacrylates, 1-(phenyl)-3-(2-methacryloyloxyethyl)-3-methyl triazene-1 (UMA-T1) and 1-(p-methoxyphenyl)-3-(2-methacryloyloxyethyl)-3-methyl triazene-1 (UMA-T2), were synthesized and characterized to be used as co-partners in the radical co-polymerization with methyl methacrylate for achieving triazene-co-polymethacrylates. The synthesized photo-polymers were spectrally and thermally characterized, the results being satisfactory for this class of materials. The most important feature of the co-polyacrylates is their photosensitivity, evaluated by the UV irradiation in DMF solution or thin films, following the disappearance of the π–π* absorption band, corresponding to the triazene chromophore, in the UV spectra. Such photolabile polymers with good film-forming properties could offer new possibilities in printing techniques and nanostructuring on surfaces. In addition, the triazene functions introduced as side-groups may be exploited for the tailoring of novel functional polymeric architectures.
