摘要：

Detailed kinetic studies into free-radical polymerization via pulsed laser experiments ideally require photoinitiators which almost instantaneously dissociate into primary free-radical fragments that rapidly add to monomer molecules and thus induce macromolecular growth. 2-Methyl-4'-(methylthio)-2-morpholinopropiophenone (MMMP) is shown to be such a suitable photoinitiator. Measurement of monomer conversion induced by a single laser pulse, within the so-called single-pulse pulsed laser polymerization (SP-PLP) experiment, provides direct information about the chain-length dependence of the termination rate coefficient if MMMP is used as the photoinitiator.
