| 摘 要： | Triad sequence distributions in a series of P(AM/AA) with different AA% were calculated from copolymerization reactivity ratio r_1 and r_2 based on first order Markov statistic model, and the calculated data compared with observed ones from ~(13)C-NMR spectra showed good agreement with each other. The sequence distribution in P(AM/AA) obtained under our experimental conditions fits in with first order Markov statistic model. A significant sequence structure difference was observed between P(AM/AA) and alkaline hydrolyzed polyaerylamide, ABA triad (acrylate unit center), AAA and AAB triads (aerylamide unit center) dominated in hydrolyzed ones.
