VOLLAROMATISCHE POLYAMIDE, VERFAHREN ZU IHRER HERSTELLUNG UND DARAUS GEFORMTE GEBILDE

Aromatic copolyamides, soluble in organic polyamide solvents, comprise at least 95 mol % of the recurrent structural units of the formulae OCArCO A B C D and up to 5 mol % of structural units containing m-bonds. Here -Ar-is a divalent, unsubstituted or substituted aromatic radical, the valency bonds...

Zusammenfassung:	Aromatic copolyamides, soluble in organic polyamide solvents, comprise at least 95 mol % of the recurrent structural units of the formulae OCArCO A B C D and up to 5 mol % of structural units containing m-bonds. Here -Ar-is a divalent, unsubstituted or substituted aromatic radical, the valency bonds of which are in the para-position or in a comparable coaxial or parallel position, and -R-and -R' are different from one another and are lower alkyl radicals or lower alkoxy radicals.
