- Abstract
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.
