Abstract

Aspects of the present disclosure generally describe polyarylether ketones and methods of use. In some aspects, a composition includes one or more polymers of formulae (I), (II), or (III):

First claim

What is claimed is:

1 . A composition comprising:
(1) a fiber material; and (2) a polymer consisting of:
at least one of

wherein each R is independently

wherein each L is independently —CH 2 —, —(CH 3 ) 2 C—, —O—, —S—, —SO 2 — or —CO—, wherein each Q is independently —S—, —SO 2 —or —(CF 3 ) 2 C—, —O—, —(CH 3 ) 2 C—, and wherein each j is a positive integer; and
a capping agent selected from

or benzyl, wherein R′ is —H, halo, C1-C20 alkyl, or cyano.

2 . The composition of claim 1 , wherein the fiber material is selected from the group comprising graphite, fiberglass, nylon, aramid polymers, and mixtures thereof.

3 . The composition of claim 1 , wherein the polymer has a glass transition temperature between about 135° C. and about 190° C.

4 . The composition of claim 1 , wherein the polymer has a melting temperature between about 200° C. and about 450° C.

5 . The composition of claim 1 , wherein the molecular weight of the polymer is between about 10 kDa and about 150 kDa.

6 . The composition of claim 5 , wherein the molecular weight of the polymer is between about 50 kDa and about 120 kDa.

7 . The composition of claim 6 , wherein the molecular weight of the polymer is between about 90 kDa and about 110 kDa.

8 . The composition of claim 1 , wherein the molecular weight of each moiety of the structure:

does not exceed about 3 kDa.

9 . The composition of claim 8 , wherein R is selected from the group comprising:

10 . The composition of claim 8 , wherein R is selected from the group comprising:

and
wherein each L is independently —CH 2 — or —(CH 3 ) 2 C—.

11 . The composition of claim 1 , wherein a ratio of
to

is between about 1:1 and about 1:2.

12 . The composition of claim 1 , wherein the moiety:

is greater than about 33 mol % of the molecular weight of the polymer.

13 . The composition of claim 12 , wherein the moiety:

is greater than about 50 mol % of the polymer.

14 . The composition of claim 1 , wherein the polymer is a block copolymer.

15 . The composition of claim 1 , wherein the polymer is a random copolymer.

16 . The composition of claim 1 , wherein the polymer is: 45 mol % of

5 mol % of benzyl capping agent; 20 mol % of

15 mol % of

and 15 mol % of

17 . The composition of claim 1 , wherein the polymer is: 48.45 mol % of

2.55 mol % of benzyl capping agent; 3.06 mol % of

9.19 mol % of

and 36.75 mol % of

18 . The comoosition of claim 1 . wherein the polymer is: 35.7 mol % of

12.75 mol % of

2.55 mol % of benzyl capping agent; 14.7 mol % of

9.8 mol % of

and 24.5 mol % of

19 . A vehicle component including the composition of claim 1 .

20 . The vehicle component of claim 20 , wherein the vehicle component is a tail cone, a panel, a coated lap joint between two or more panels, a wing-to-fuselage assembly, structural aircraft composite, fuselage body-joint or wing rib-to-skin joint.
