Abstract
Procedure for obtaining aromatic copolyamides, of high molecular weight, which are composed of 1-95 mol-% of structural units containing hydantoin rings of general formula -NH-X-Hy-Y-Z-NH-OC-Ar-CO- (I) in which Z means a single bond or the grouping -Hy-X- and X and Y may be the same or different and signify bivalent residues that are made up of one or more condensed rings or of several aromatic rings that are linked together by bonds singles or by bridge members such as **(See formula)** as well as its halogen, C1 to C4-alkyl, NO2 or CN substitution products, where Hy means a bivalent hydantoin ring of formula **(See formula)** R represents hydrogen, C1- to C4-alkyl, cycloalkyl or a phenyl radical, optionally substituted, and Ar means a bivalent aromatic radical, which is made up of one or more condensed rings or several aromatic rings, which are linked by single bonds or by bridge members such as (see formula) as well as its halogen, C1- to C4-alkyl, NO2 or CN substitution products, which in 99 - 90.5 mol-% are made up of structural units of general formula -HN-Ar'-NH-OC-Ar-CO- (II) where Ar has the meaning indicated above and Ar'has the meaning indicated for X, the copolyamides showing a relative viscosity in solution η rel (measured in a 0.5% solution of the copolyamides in concentrated sulfuric acid at 25ºC) 1,2-2,5, by polycondensation of aromatic diamines with aromatic dicarboxylic acid halides in polar organic solvents, characterized in that aromatic dicarboxylic acid halides of general formula HalOC-Ar-COHal (III) where Hal means Cl or Br and Ar has the meaning indicated in claim 1, they are polycondensed with 1-9.5 mol-% of diamines containing hydantoin rings of general formula H2N-X-Hy-Y-Z-NH2 (IV) in which Hy, X, Y and Z have the meaning indicated in claim 1, and 90.5-99 mol-%, in each case referred to the total amount of diamine, of aromatic diamines of general formula H2N-Ar'-NH2 (V) in which Ar'has the meaning indicated in claim 1, in polar organic solvents at temperatures between -30 and + 150ºC.
