Analysis of the 1H-NMR and 13C-NMR spectra of poly(3-methyl-1-vinylpyrazole)

Summary

The title monomer was polymerized in solution via free radical initiation. The polymer's 300 MHz 1H-NMR and 75.5 MHz 13C-NMR spectra were recorded and analyzed in terms of polymer stereochemistry. Most of the resonances in both the 1H-NMR and 13C-NMR spectra showed multiplicity consistent with sensitivity to polymer stereochemistry. However the 13C-NMR spectrum proved somewhat easier to interpret. The analysis of both the 1H-NMR and 13C-NMR spectra very strongly indicate that poly(3-methyl-1-vinylpyrazole) is an atactic polymer.
