The preparation of polymeric UV stabilizers by copolymerization of polymerizable UV stabilizers like 2-(2-hydroxy-5-vinylphenyl)-2H-benzotriazole (2H5V) and 2-(2-hydroxy-5-isopropenylphenyl)-2H-benzotriazole (2H5P) with styrene (S), methyl methacrylate (MMA), and butyl acrylate (BA) was studied. Copolymerization parameters for six pairs of monomers, i.e. 2H5V-S, 2H5V-MMA, 2H5V-BA, 2H5P-S, 2H5P-MMA, and 2H5P-BA and UV spectra of the 2H5P copolymers were determined. The effect of stiffness of the polymer chain on UV spectra of copolymers studied is discussed.
