Description
Summary:A new diol‐functionalized triazine‐based polymerizable hindered amine light stabilizer (HALS) was synthesized in two steps. First, selective synthesis of an s‐triazine containing two HALS moieties as substituents was accomplished by using phase‐transfer catalysis. This step required the establishment of optimum reaction conditions (type of two‐phase system, best solvent, and catalyst). In the second step, the substituted triazine was treated with diethanolamine to introduce polymerizable diol functionality. The resulting product should act as a light stabilizer, since it contains two HALS moieties anchored to a thermally stable s‐triazine unit. Moreover, incorporation of the diol into a polymeric material might be expected to impart prolonged stability in weathering environments. Characterization of the diol was accomplished by using Fourier transform infrared spectroscopy (FTIR), 'H NMR, and mass spectrometry. J. VINYL ADDIT.
