- Abstract
The precise knowledge of rate coefficients is of key importance for the understanding and the application of radical polymerization processes. Propagation rate coefficients, kp, of n‐pentyl methacrylate (PnMA) radical polymerization are measured in bulk and partly in toluene solution over an extended temperature range via pulsed laser polymerization (PLP) in conjunction with size‐exclusion chromatography (PLP–SEC). Rate coefficients, kti,i, for termination of two radicals of chain length i are determined as a function of chain length by single‐pulse PLP in conjunction with electron paramagnetic resonance spectroscopy (SP–PLP–EPR). The as‐obtained data that allow for modeling PnMA polymerization kinetics and product properties at moderate degrees of monomer conversion are compared with reported data for several other alkyl methacrylates. A distinct family behavior of this group of monomers is seen.
