Abstract

The free-radical copolymerization of acrylonitrile and methacrylic acid has been investigated in bulk at 60 °C with the aim of elucidating the best model for the polymerization. Quantitative measurements of the copolymerization compositions and diad, triad, and tetrad fractions in the comonomer sequence distribution have been determined by using elemental analysis and 1H, 13C, and l3C DEPT NMR. This microstructural information was found to be consistent with a terminal polymerization mechanism with rM= 3.7 and rA = 0.19. The penultimate model was not found to provide a statistically significant improvement over the terminal model.
