eng	The use of covalently bound stabilizers in polymer chemistry	The presented work deals about covalent linkage stabilizers against photooxidative degradation of the structure of the polymer. The compounds prepared were characterized in individual steps of the synthesis by elemental analysis, where were found percentages of C, H, N, by 13C NMR and 1H NMR and different values of molecular weights were determined by gel permeation chromatography. Further, the fluorescent label are established and have been investigated its UV / VIS absorption and fluorescence spectra in 1,4-dioxan and in the solid phase. Were prepared coatings, which were subjected to accelerated aging in a QUV panel for 800 hours. From the above experiments it is evident that covalently bonded stabilizers cause an increase in the resistance of the system against UV radiation.	stabilizer; fluorescence; antidegradant; HALS
