Abstract

Heat-resistant, high strength fibers useful in a wide range of end-use applications are prepared using a polymeric composition containing polyetherketoneketone and mineral nanotubes.

First claim

What is claimed is:

1. A fiber consisting of:
a) polyetherketoneketone,
wherein the polyetherketoneketone is comprised of repeating units represented by formulas I and II:
-A-C(═O)—B—C(═O)—  I

-A-C(═O)-D-C(═O)—  II

wherein A is a p,p′-Ph-O-Ph- group, Ph is a phenylene radical, B is p-phenylene, and D is m-phenylene and the isomer ratio of formula I:formula II (T:I) is about 60:40,
and wherein the polyetherketoneketone has a crystallinity, as measured by DSC, of from about 10 to about 40%
b) mineral nanotubes, and
c) optionally, one or more additives selected from the group consisting of stabilizers and processing aids.

2. The fiber of claim 1 , wherein said fiber is a monofilament.

3. The fiber of claim 1 , wherein said fiber is a multifilament.

4. The fiber of claim 1 , wherein said fiber has a diameter of about 50 microns to about 2 mm.

5. The fiber of claim 1 , wherein said fiber is comprised of 0.01 to 30 weight percent mineral nanotubes.

6. A woven fabric comprising a plurality of fibers in accordance with claim 1 .

7. A non-woven fabric comprising a plurality of fibers in accordance with claim 1 .

8. A yarn comprising a plurality of fibers in accordance with claim 1 .

9. A braid comprising a plurality of fibers in accordance with claim 1 .

10. An implantable braided device comprised of a plurality of fibers in accordance with claim 1 .

11. The fiber of claim 1 wherein said mineral nanotubes are inorganic nanotubes.

12. The fiber of claim 1 consisting of said polyetherketoneketone and mineral nanotubes.

13. A fiber consisting of:
a) polyetherketoneketone,
wherein the polyetherketoneketone is comprised of repeating units represented by formulas I and II:
-A-C(═O)—B—C(═O)—  I

-A-C(═O)-D-C(═O)—  II

wherein A is a p,p′-Ph-O-Ph- group, Ph is a phenylene radical, B is p-phenylene, and D is m-phenylene and the isomer ratio of formula I:formula II (T:I) is about 60:40,
wherein the polyetherketoneketone is amorphous,
b) mineral nanotubes, and
c) optionally, one or more additives selected from the group consisting of stabilizers and processing aids.
