摘要：

The propagating radical in the emulsion polymerization reaction of butyl acrylate was detected by Electron Paramagnetic Resonance (EPR) spectroscopy using two spin-trapping agents, 2-methyl-2-nitrosopropane (MNP) and alpha-(4-pyridyl 1-oxide)-N-tert-butylnitrone (PyOBN). Through analysis of hyperfine structure of the spectra obtained from the trapped radicals, the propagating radical is inferred to be the well known acrylate radical, -[CH2-CH(COOC4H9)](n)-CH2-CH(COOC4H9)-.
