The microstructural analysis of poly(α-tocopherylmethacrylate) (PMVE) was carried out by one-dimensional 13 C n.m.r. spectroscopy. The sensitivity of both aromatic and methyl (those attached to the aromatic ring) carbon signals to the stereosequences depends mainly on the proximity of these carbons to the maximum shielding zone of the neighbouring conjugated blocks formed by the aromatic ring...
The microstructural analysis of both poly(4-N-acrylamide-2-hydroxybenzoic acid) (poly(4-AHA)) and poly(5-N-acrylamide-2-hydroxybenzoic acid) (poly(5-AHA)) was carried out by one-dimensional 13C n.m.r. spectroscopy. The sensitivity of aromatic carbon signals to the stereosequences was found to depend mainly upon the carbon ability to extend into the maximum shielding zone of the neighbouring phenyl...
