Synthesis of polymers with protogenic groups by polymer-analogous transformations

The main achievements in the synthesis of polymers containing sulfonic and phosphoric acid groups by polymer-analogous transformations are analysed. Two key methods for the introduction of these groups are considered, namely, metallation of the initial polymers followed by functionalisation and modification of the reactive fragments of macromolecular chains. The attention is focussed on the properties of the polymeric materials obtained in this way.
