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

As a highly reactive tactic vinyl polymer, syndiotactic poly(methacrylic acid hydrazide) (s-PMH) was prepared from syndiotactic poly(methyl methacrylate) (s-PMMA) by hydrazinolysis. The s-PMH served as the starting polymer to prepare other tactic vinyl homopolymers having optically active functional

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
