摘要：
Acrylonitrile/butyl methacrylate (A/B) copolymers were prepared in bulk with different comonomer feed ratios. The copolymer composition obtained from the total nitrogen content was used for calculating the reactivity ratios. Information about sequence distributions was obtained from C-13 NMR spectroscopy. The relative amounts of A- and B-centred triads were evaluated by using nitrile (-CN) and carbonyl (-CO) carbon resonances, respectively, and have been found to be in a good agreement with those expected theoretically.
