The polycondensation of terephthalaldehyde with 2‐amino‐2‐methyl‐1,3‐propanediol using acidic catalysts leads to the formation of linear polymers and macrocyclic compounds with 2‐(1′,4′‐phenylene)‐5‐methyl‐1‐aza‐3,7‐dioxabicyclo[3.3.0]octane as the repeating unit in all compounds. The structure of the polymer was determined by 1 H‐ and 13 C‐NMR spectroscopy, and electrospray ionization mass spectrometric (ESI‐MS) analysis. ESI‐MS measurements were used to study the details of the polymer structure and support the equimolar alternating nature of bicyclo‐ O,N ‐acetals of terephthaldehyde in these macromolecules.
