Summary
The 300 MHz 1H-NMR and 75.5 MHz 13C-NMR spectra of poly(2-iodostyrene) were recorded and analyzed in terms of polymer stereochemistry. The aromatic protons were insufficiently resolved for any reasonable peak assignments to be made, but the methine proton resonance could be interpreted in terms of a pentad stereosequence sensitivity. The analysis suggested poly(2-iodostyrene) was an atactic polymer. The 13C-NMR spectrum was somewhat better resolved and analysis supports the results from the 1H-NMR i.e. poly(2-iodostyrene) is an atactic polymer.
