An analysis of the 1H-NMR and 13C-NMR spectra of poly(3-methyl-2-vinyl thiophene)

Abstract

The title polymer was synthesized by free radical initiation in bulk. The 300 MHz H-NMR and 75 MHz 13C-NMR spectra of the polymer were obtained at ambient temperature and analyzed in terms of stereochemistry. The H-NMR spectrum provides limited information but suggests that the polymer is atactic. Analysis of the more detailed 13C-NMR spectrum supports this result, i.e. poly(3-methyl-2-vinyl thiophene) is an atactic polymer.
