The polycondensation of terephthalaldehyde with 2‐amino‐2‐hydroxymethyl‐1,3‐propanediol (TRIS), or of terephthaldehyde with 2,2′‐(1,4‐phenylene)‐bis‐1,3‐(4,4‐dihydroxymethyl)oxazolidine (bis‐oxazolidine), using acidic catalysts, leads to the formation of linear polymers and macrocyclic compounds. The structure of the polymer was determined by 1 H‐, 13 C‐NMR spectroscopy and electrospray ionization mass spectrometry (ESI‐MS) analysis. ESI‐MS measurements were used to study the details of the polymer structure and support the alternating nature of equimolar amounts of oxazolidine and the cyclic acetal of terephthaldehyde in these macromolecules.
