Abstract
Abstract The present invention relates to polycondensates of the formula 10, their use for absorbing metal ions of the transition elements of the periodic system and their use for the preparation of polymers containing metals of formula 11 which have e.g. improved resistance to heat and to chemicals compared to the corresponding polycondensates of formula 10.
