Abstract
Poly(arylene ether)ketones, polyamides, and poly(benzoxazoles) that contain thiophene rings within the aromatic polymer backbone are disclosed, along with fibers, films, and other articles of manufacture formed therefrom.
Claims18
A poly(arylene ether ketone) comprising repeating units of the formula:
- --[AB]-- (I)
- wherein A comprises an aromatic diphenol having at least one aromatic ring;
- wherein B comprises an aromatic ketone unit containing at least two aromatic rings joined by a ketone linkage, one of said at least two aromatic rings comprising a thiophene ring;
- and wherein each of said aromatic ketone units is linked at each end thereof to a phenolic oxygen of one of said aromatic diphenols to form an ether linkage.
