The radiation polymerization of ethyl acrylate (EA) and hydroxyethyl a
crylate (HEA) monomers was studied in aqueous solution, The absorption
spectra taken after a 2.6 mu s pulse in N2O saturated acidic solution
of EA and HEA are shown to have maxima at 300 nm. Average values of r
ate parameters were calculated from after effect measurements. A compu
ter program based on numerical integration tvas applied in order to es
timate individual rate parameters.
