Abstract
The present invention provides curable polyimides with low color that are resistant to long term thermo-oxidative degradation. These materials, which include polyimides that are fully aromatic, are synthesized in anisole and are contemplated for use in high temperature applications such as in the aerospace industry and for use as encapsulants for light emitting diodes that will be exposed to high temperatures.

1-85. (canceled)
A thermo-oxidation-resistant composition comprising at least one compound having a structure according to the following Formula I:
- wherein,
- R is selected from the group consisting of fluorinated aromatic, substituted aromatic, unsubstituted aromatic, and heteroaromatic moieties, and combinations thereof;
- Q is selected from the group consisting of fluorinated aromatic, substituted aromatic, unsubstituted aromatic, and heteroaromatic moieties, and combinations thereof;
- X is a curable moiety, optionally selected from the group consisting of benzoxazines, maleimides, citraconimides, itaconimide, and combinations thereof;
- and
- n is 0 or an integer having the value from 1-100 or an integer having the value from 20-100;
- with the proviso that no R or Q contains any primary, secondary, tertiary or benzylic hydrogen atoms;
- and
- optionally comprising a solvent, wherein the solvent is optionally anisole.
