Abstract

The radical copolymerization of α-terpineol with N-vinylpyrrolidone (N-VP) in dioxane at (80 ± 0.1)°C for 1 h in the presence of benzoylperoxide follows ideal kinetic and results in the formation of random copolymer as evidenced from the value of reactivity ratios as r1 (N-VP) = 0.23 and r2 (α-terpineol) = 0.025, which have been calculated by the Kelen-Tüdos method. The overall activation energy is computed to be 28 kJ/mol. The FTIR spectrum of the copolymer shows the presence of bands at 3507 cm−1 due to alcoholic group and 1717 cm−1 due to > CO group. The Alfrey-Price parameters for α-terpineol has been calculated as 0.024 and –2.66. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 476–481, 2007
