Abstract: IN THE MANUFACTURE OF COPOLYESTERS FROM TEREPHTHALIC ACID OR THE LOW MOLECULAR WEIGHT ALKYL ESTERS THEREOF AND ETHYLENE GLYCOL, DEFINITE MERCAPTALS AND/OR THIOKETALS ARE INCORPORATED INTO THE MACROMOLECULE BY ESTER LINKAGE. THE POLYESTERS ARE SHAPED FROM THE MELT AND SULFONIC ACID GROUPS ARE PRODUCED IN THE SHAPED STRUCTURES BY AN OXIDATIVE AFTER-TREATMENT. THE STRUCTURES HAVE A HIGH AFFINITY FOR CATIONIC SUBSTANCES.

Abstract: Aromatic copolyamides, soluble in organic polyamide solvents, comprise at least 95 mol % of the recurrent structural units of the formulae OCArCO A HNAr'NH B C D and up to 5 mol % of structural units containing m-bonds. -Ar- and -Ar'- are here divalent, unsubstituted or substituted aromatic radicals, 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.

Abstract: Aromatic copolyamides, preparation thereof and structures formed therefrom There are described aromatic copolyamides which are soluble in organic solvents for polyamides and which comprise at least 95 mol % of recurring structural units of formulae OCArCO A NHAr'NH B C D and up to 5 mol % of meta-bonded structural units E and/or F derived from aromatic dicarboxylic acids (E') and/or from aromatic diamines (F'), the sum total of the mole fractions of structural units A+E and the sum total of the mole fractions of structural units B+C+D+F being essentially of equal magnitude. The copolyamides of the present invention can be processed into fibers having high strengths and high breaking extensions.

Abstract: 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.

Abstract: Aromatic copolyamides are described, which are soluble in organic amide solvents. The polymers are composed to at least 95 mol % of repeat structural units A: -OC-AR-CO- B: -HN-Ar'-NH- C: -HN-Ar''-NH- in the combinations A+B+C+D, or A+C+D+E and up to 5 mol % of m-bond-containing structural units F and/or G derived from aromatic dicarboxylic acids (F') and/or from aromatic diamines (G'), the sum total of the mole fractions of structural units A+F and the sum total of the mole fractions of the structural units of B+C+D+E+G being essentially the same, -Ar- and -Ar'- are divalent aromatic radicals whose C-N valence bonds are in a para-position or in a similar coaxial or parallel position and which may be substituted by one or two inert radicals, such as lower alkykl or halogen, is a trivalent aromatic radical which after removal of the -SO2R group has the same meaning as -Ar- or -Ar'- or else is the structural unit wehre X is -O-, -NHCO-, -SO2- or -CO-, -R is lower alkyl and -R' is lower alkyl or alkoxy, and the proportions of the diamine components B, C, D and E are within the following limits: B: 25-47.5 mol % C: 7.5-30 mol D: 45-67.5 mol and E: 20-40 mol.
