Condensation polymerization of triphenylamine with carbonyl compounds
Triphenylamine (TPA) was reacted with carbonyl compounds such as formaldehyde, butyraldehyde, benzaldehyde, and acetone in the presence of an acid catalyst. 1H and 13C NMR spectra revealed that the carbonyl compounds react only at the p‐position of TPA. The reactivity of formaldehyde with TPA is low...

Summary: | Triphenylamine (TPA) was reacted with carbonyl compounds such as formaldehyde, butyraldehyde, benzaldehyde, and acetone in the presence of an acid catalyst. 1H and 13C NMR spectra revealed that the carbonyl compounds react only at the p‐position of TPA. The reactivity of formaldehyde with TPA is lower than that with phenol. If equal molar amounts of formaldehyde are reacted, however, TPA condensation proceeds to high molecular weight polymers, while phenol provides only low molecular weight compounds (up to 1 000). TPA‐aldehyde polymers have glass transition temperatures in the range of 135 – 176°C. These polymers show good solubility and sufficient stability after film formation. |
