摘要： An aromatic poly(thioetheramide-imide) has a recurring unit of the following general formula (II):
wherein each -Ar-, which may be the same or different represents a divalent aromatic residue.
Preparation is by reacting an aromatic diamine H₂N-C₆H₄-S-Ar-S-C₆H₄-NH₂ with trimellitic anhydride or its chloride, preferably in a polar organic solvent in the presence of a HCl trapping agent, followed by dehyd­ration.
The polymer is moldable optionally with a filler, to form a shaped product, film or fibres of good strength.
