Abstract
Pulsed laser polymn. (PLP) of cyclohexyl acrylate (CHA) was carried out to optimize the PLP conditions for detn. of consistent propagation rate coeffs. (kps). Concurrence of mid-chain radicals (MCRs) formed primarily by backbiting and propagating radicals as an unavoidable feature of acrylate polymn. for kinetic study was confirmed by ESR spectroscopy. The mol. wt. distributions (MWDs) of the resultant polymers measured by GPC were carefully inspected to exclude the influence of the low reactivity and b-fragmentation of MCR in order to obtain consistent values of kp. The PLPs at the low initiator concns. where the influence of MCR could be minimized were found to give MWDs suitable for kp detn. The kp values obtained for CHA were comparable with reported values for other acrylic esters. [on SciFinder (R)]
