Effect of tacticity of poly(acrylonitrile-co-itaconic acid) on the thermal oxidative stabilization behavior |
| 초록 |
Stereoregular polyacrylonitrile and poly(acrylonitrile-co-itaconic acid) were prepared through the complex formation between monomers and Lewis Acid during their free radical polymerization processes. Isotacticity values of the polymers were determined by 13C-NMR. FT-IR was employed for the quantitative tracking of the structural evolution of the polymer films during their thermal oxidative stabilization (TOS) processes. Cyclization, oxidation and tautomerization during TOS process were characterized and quantified by the evolution of overlapping peaks of cyclic C=C, C=N, N−H and C=O vibrations in FT-IR. Stereoregularity in the copolymers played an important role for more facile TOS processes. |
