Critically evaluated propagation rate coefficients in free-radical polymerizations: Part III. Methacrylates with cyclic ester groups (IUPAC Technical Report)

Abstract: Propagation rate coefficients, kp,
as a function of temperature, are reported for bulk free-radical homopolymerizations
of oxiranylmethyl, cyclohexyl, and benzyl methacrylate at ambient pressure
and low conversion. The data were obtained from experiments combining
pulsed-laser initiated polymerization and
size-exclusion chromatography. The data determined from experiments
carried out in independent laboratories obey the consistency criteria
established for this technique. The rate coefficients for the three
monomers are well represented by a single Arrhenius relation.
