Abstract:
A polyarylene fiber including 0.1-15% based on the weight of the fiber of an aromatic compound or a combination of aromatic compounds wherein each aromatic compound comprises an aromatic core and at least one of the substituents A or B, where A is represented by formula 1 Error! Reference source not found. and B is represented by formula 2 Error! Reference source not found. Also, a spin dope and a process for manufacturing a polyarylene fiber.

Claim (Index 15):
A process to manufacture a polyarylene fiber with improved hydrolytic stability comprising the steps:\n i) preparing a composition comprising polyarylene polymer, a solvent and a compound or combination of compounds, ii) processing the composition to obtain the polyarylene fiber, wherein each compound comprises an aromatic core and at least one of the substituents A or B, where A is represented by formula 1 and B is represented by formula 2 wherein R1 and R2 are independently of each other selected from an alkanediyl comprising 2 to 10 carbon atoms; wherein R3 and R4 are independently of each other selected from \u2014H, alkyl comprising 1 to 10 carbon atoms, homocycloalkyl comprising 3 to 10 carbon atoms or heterocycloalkyl comprising 1 to 10 carbon atoms; wherein R5 is selected from: \u2014H, alkyl comprising 1 to 10 carbon atoms, homocycloalkyl comprising 3 to 10 carbon atoms, heterocycloalkyl comprising 1 to 10 carbon atoms, and a carbonyl (\u2014C(\u2550O)\u2014 which forms a phthalimido ring structure fused to the aromatic core.
