Abstract: The copolymerizations of acrylates including: methyl acrylate(MA), methyl methacrylate(MMA), isobornyl methacrylate(IBMA) with different N-arylmethacrylamides including: N-Phenylmethacrylamide (N-PhMA), N-p-Tolylmethacrylamide (N-p-TMA), N-o-Tolylmethacrylamide (N-o-TMA), N-p-Bromophenylmethacrylamide (N-p-BrPhMA), N-p-Chlorophenylmethacrylamide (N-p-ClPhMA), N-p-Nitrophenylmethacrylamide (N-p-NPhMA), N-o-Nitrophenylme-thacrylamide (N-o-NPhMA), N-α-Naphthylmethacrylamide (N-α-HMA) were studied by means of ¹H-NMR method. The composition of the copolymers including: MA-co-N-ArMA, MMA-co-N-ArMA, IBMA-co-N-ArMA were determined from the peak areas of the phenyl group and methoxy group in the ¹H-NMR spectra. Reactivity ratios were calculated from the composition data by the Fineman-Rossmethod. The activity of various N-ArMA with MA, MMA and IBMA were investigated.
