Abstract

Claims (24)

1. A thermoplastic composition comprising:

polyetherimide polymer; and

a polyaryletherketone polymer, wherein the polyaryletherketone polymer is one of polyether ketone ketone polymer or a blend of polyether ketone ketone polymer and polyether ether ketone polymer,

wherein a ratio of the polyetherimide polymer to the polyaryletherketone polymer is between about 1:20 and 1:9,

wherein the thermoplastic composition comprises a degree of crystallinity from 3 percent to about 30 percent.

2. The thermoplastic composition of claim 1 wherein the polyaryletherketone polymer comprises a blend of polyether ketone ketone and polyether ether ketone.

3. The thermoplastic composition of claim 2 comprising a degree of crystallinity from 3 percent to about 15 percent.

4. The thermoplastic composition of claim 2 comprising a degree of crystallinity from 3 percent to about 10 percent.

5. The thermoplastic composition of claim 1 comprising a degree of crystallinity from 3 percent to about 15 percent.

6. The thermoplastic composition of claim 1 comprising a degree of crystallinity from 3 percent to about 10 percent.

7. The thermoplastic composition of claim 1 wherein the polyaryletherketone polymer has a melting temperature of about 275° C. to about 350° C.

8. The thermoplastic composition of claim 1 wherein the polyaryletherketone polymer has a melting temperature of at least about 300° C.

9. The thermoplastic composition of claim 1 further comprising a heat stabilizer.

10. The thermoplastic composition of claim 1 further comprising a nucleating agent.

11. A film comprising the thermoplastic composition of claim 1 .

12. The film of claim 11 comprising a thickness of about 1 mil to about 15 mil.

13. The film of claim 11 wherein the polyaryletherketone polymer comprises a blend of polyether ketone ketone and polyether ether ketone.

14. The film of claim 13 comprising a degree of crystallinity from 3 percent to about 15 percent.

15. The film of claim 13 comprising a degree of crystallinity from 3 percent to about 10 percent.

16. The film of claim 11 comprising a degree of crystallinity from 3 percent to about 15 percent.

17. The film of claim 11 comprising a degree of crystallinity from 3 percent to about 10 percent.

18. The film of claim 11 wherein the polyaryletherketone polymer has a melting temperature of about 275° C. to about 350° C.

19. The film of claim 11 wherein the polyaryletherketone polymer has a melting temperature of at least about 300° C.

20. The film of claim 11 wherein the thermoplastic composition further comprises a heat stabilizer.
