Abstract
Methacrylonitrile/methylmethacrylate (A/M) copolymers were prepared by bulk polymerization. The 13C DEPT-135 (distortionless enhancement by polarization transfer) spectrum was used to differentiate between the carbon resonance signals of methyl, methoxy, and methylene units in the copolymers (A/M). Comonomer reactivity ratios were determined using Kelen–Tudos and non-linear error in variable methods. 2D heteronuclear single quantum correlation (HSQC) and total correlated spectroscopy (TOCSY) spectra were used to resolve the complex 1H NMR spectrum.
