Abstract

The invention relates to amorphous polyesterimides which comprises 50 to 100 mole-% of units of formula II ##STR1## and from 0 to 50 mole-% of units of formula ##STR2## in which units R.sub.1 and R.sub.2, independentlyof one another, are H, branched or unbranched alkyl radicals having 1 to 6 carbon atoms, branched or unbranched alkoxy radicals having 1 to 6 carbon atoms, or F, Cl or Br. The polyesterimides according to the invention are suitable for the production of molding compositions, moldings, fibers and films.
