Abstract
Abstract The radical polymerization of phenyl acrylate (PhA) in various aromatic solvents was studied under the same conditions as that of phenyl methacrylate (PMA) reported previously. The propagation rate constants (kp ) and termination rate constants (kt ) were determined by intermittent illumination methods. The variation in the kp values for PhA with aromatic solvents had the same trend as that for PMA. The solvent effect on PhA was somewhat larger than that on PMA, indicating that the steric hindrance of methyl group of the latter is important. Variation in kp values with solvents can be explained by the formation of an electron donor-acceptor complex and is correlated with the derealization stabilization of complex formation.
