Abstract
Copolymerization of cyclohexyl acrylate (CHA) with styrene (Sty) and N-vinyl-2-pyrrolidone (VPD) was carried out in benzene and dioxane at 70°C and 75°C, respectively, using benzoyl peroxide as initiator. The copolymers were characterized by i.r., 1H n.m.r., g.p.c. and viscometry. The compositions of the copolymers were determined by elemental analysis and the reactivity ratios were computed by Fineman-Ross, Kelen-Tudos and extended Kelen-Tudos methods. r CHA = 0.272 ± 0.048, r Sty = 0.913 ± 0.107 for CHA-Sty system and r CHA = 1.297 ± 0.088, r VPD = 0.122 ± 0.014 for CHA-VPD system are determined by extended Kelen-Tudos method. The Q and e values for CHA monomer were also determined.
