The partial esterification of syndiotactic poly(methacrylic acid) with benzyl alcohol or trifluoroethanol and dicyclohexylcarbodiimide as a condensing agent has been studied, evaluating triad and pentad probabilities by 1H-NMR. The mechanism of this esterification leads to a tendency toward alternat

## Abstract Phenyl methacrylate and __p__‐tolyl methacrylate were synthesized by starting directly from methacrylic acid and the corresponding phenols. Polymer‐analogous esterification on poly[ethylene‐__co__‐(acrylic acid)] (PEAA) was performed with phenol, __p__‐methoxyphenol, and 2,4,6‐trimethyl

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
