Notes:
The infrared spectra of several alcohols and aminoalcohols were measured in bulk and in dilute solution in the 2800-4000 cm.-1 region to determine the nature of hydrogen bonding in these compounds. An epoxy resin was cured with both an aliphatic monoamine and a diamine, and the OH-stretching bands of the polymers were studied in the temperature range 30-200°C. It is concluded that the hydroxyl groups in the polymers are extensively involved in long-range hydrogen bonding, particularly of the O—H—N type, at room temperature. The shift in the bonded OH band to lower frequency with increasing temperature is attributed to a shift from long range to short range bonds. Even at 200°C. there are relatively few free hydroxyl groups in these polymers.
