摘要
New linear polyimides 11 were synthesized via Diels-Alder addition polymerization of alpha-pyrones 9 with bismaleimides 10. The number-average molecular weights M(n)BAR range from 10000 to 34000 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.
