After-effect of pressure to the ESR spectra of irradiated PMMA

Journal Article · · Polym. J., v. 4, no. 2, pp. 120-123

Changes in the structure of 9-line ESR spectrum of irradiated PMMA to which the pressure of 5000 atm has been applied are studied. Thc original 9-line spectrum gradually changes so that other component spectra (i.e., singlet, doublet, and quartet) start to prevail. These spectra correspond to polyene radicals, chain radicals of the type --(CH/sub 3/)C(COOCH/sub 3/)-CH--(CH/sub 3/ )C(COOCH/sub 3/) -- and allyl radicals. (auth)
