Unusual assignments have been observed for the 1H-NMR of alkoxy groups in syndiotactic methyl methacrylate-methacrylic acid (MMA-MAA) copolymers and methyl methacrylate-diphenylmethyl methacrylate (MMA-DPMMA) copolymers. Thereby, the alkoxy groups --OCH3 and --OCH < show a degenerate pentad assignme
## Abstract The NMR spectra of methyl methacrylate–styrene and methyl methacrylate–α‐methylstyrene copolymers exhibit, among other features of interest, an unexpected multiplicity in the 6.4–7.8 τ region, characteristic of methoxyl protons. This multiplicity is believed due to magnetic shielding by
