Claims
- 1. A polyimide composition comprising recurring units of ##STR4## wherein Ar is selected from the group consisting of ##STR5##
- 2. A polyimide solution containing the polymer of claim 1.
- 3. A structure comprising at least one substrate coated with at least one layer of the polyimide composition of claim 1.
- 4. The structure of claim 3 having two or more layers of the polyimide of claim 1.
- 5. A polymer composition comprising recurring units of ##STR6## wherein R.sup.1 and R.sup.2 are independently selected from halogen, --OH, and --OR.sup.3 where R.sup.3 is an alkyl group 1 to 4 carbon atoms; and wherein Ar is selected from the group consisting of ##STR7##
- 6. A structure comprising at least one substrate coated with at least one layer of the polyimide composition of claim 5.
- 7. The structure of claim 6 having two or more layers of the polyimide of claim 5.
- 8. The polymer composition of claim 5 wherein R.sup.1 and R.sup.2 are each chlorine.
- 9. A polyimide solution containing the polymer of claim 5.
