Preliminary analysis of the H-1- and C-13-NMR spectra of poly(3-vinyl-1-methylindole)

The title monomer was synthesized and polymerized via free radical initation. The high field H-1- and C-13-NMR spectra were recorded and analyzed. Many resonances displayed multiplicities indicating a sensitivity to polymer stereochemistry but, in most cases, the resolution was insufficient for any reasonable interpretations to be made. The resonances that were well enough resolved for relatively accurate measurements to be made were analyzed in terms of polymer stereochemistry. The analysis suggests that poly(3-vinyl-1-methyl-indole) is an atactic polymer.
