Abstract:
The invention relates to nitrogen-containing polymers containing structural units of formula (I), ##STR1## where the symbols and indices have the following meanings: Ar.sup.1, Ar.sup.2, Ar.sup.3 are, identically or differently, mono- and/or polynuclear and/or condensed aryl and/or heteroaryl groups which may or may not be linked via one or more bridges carbon atoms, which may or may not be substituted;X is a single bond, --O--, --S--, --SO--, --SO.sub.2, NR.sup.3, --CR.sup.4 R.sup.5 --, --CO--, --CR.sup.6 .dbd.CR.sup.7, CR.sup.8 R.sup.9 --CR.sup.10 R.sup.11 or SiR.sup.12 R.sup.13 ;R.sup.1 -R.sup.13 are, identically or differently, H, a hydrocarbon radical having from 1 to 22 carbon atoms or Ar.sup.4, where Ar.sup.4, identical with or different from Ar.sup.1, has the same meanings as Ar.sup.1 ;n=1, 2 or 3.
