Copolymerization of 2-[3-(2H-Benzotriazol-2-yl)4-Hydroxyphenyl]Ethyl Methacrylate with Styrene

Original language description

Radical copolymerization of 2-[3-(2H-benzotriazol-2-yl)-4-hydroxyphenyl]ethyl methacrylate ( M-1) with styrene ( M-2) at 70 degrees C in 1,4-dioxane was investigated and the reactivity ratios were determined. The copolymerization was carried out as batchcopolymerization to a low conversion or as copolymerization with a continuous addition of monomers at higher instantaneous conversion. The monomer reactivity ratios of the copolymerizable UV stabilizer 2-[ 3-( 2H- benzotriazol- 2- yl)- 4- hydroxyphenyl]ethyl methacrylate with styrene were determined using the Finemann-Ross plot for both copolymeration techniques. The estimated reactivity ratios were r(1) = 0.588 and r(2) = 0.6 for the technique of continuous addition of monomers and r(1) = 0.462 and r(2) = 0.476 and for the batch experiment. The copolymerization exhibited an azeotrope at f(1) = 0.507, thus a copolymer with microstructure close to the alternating one was formed at this ratio of comonomers.
