Notes:
New linear polyimides 11 were synthesized via Diels-Alder addition polymerization of α-pyrones 9 with bismaleimides 10. The number-average molecular weights Mn range from 10 000 to 34 000 g. mol (gel-permeation chromatography). The chemical structure of these polymers is supported by X-ray crystallography, NMR spectra and model reactions. The Diels-Alder addition occurred with high endo selectivity.
