摘要：

The precise knowledge of rate coefficients is of key importance for the understanding and the application of radical polymerization processes. Propagation rate coefficients, k(p), 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, k(t)(i)(,)(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.
