The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60 ?C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios were calculated, rITA = 1.35?0.11; rMMA = 0.22?0.22 (by the Fineman-Ross method) and rITA = 1.27?0.38; rMMA = 0.10?0.05 (by the Mayo-Lewis method). The synthesised copolymers were modified by reaction with di-n-butyl amine. The copolymer composition after amidation was determined by elemental analysis via the nitrogen content. Amidation of the anhydride units in the copolymers with di-n-butyl amine resulted in complete conversion to itaconamic acid.
