Abstract
AbstractThe choice of the photoinitiator is not usually regarded as being as important consideration in attempting to determine the value of the propagation rate coefficient kp from a pulsed laser‐initiated polymerization (PLP). It is shown that in fact the choice of the photoinitiator can profoundly influence the success of such experiments. Specially, for a number of monomers it was found that the successful determination of kp is essentially impossible when 1,1‐azodicyclohexanecarbonitrile is employed as a photoinitiator. The likely reason for this phenomenon is discussed from which it would seem appropriate to be wary in using any azo compound as a PLP photoinitiator. From PLP experiments with a non‐azo photoinitiator, ambient pressure kp has been determined for bulk polymerization of methyl methacrylate over an extended temperature range.
