Ordered condensation polymers from symmetrical in situ and/or isolated intermediates - A review

Different syntheses of ordered condensation polymers from nonsymmetric monomers are reviewed. For several classes of polymers, the approach exploiting reactivity differences between the functional groups of the nonsymmetric monomers (ordered polymers from in situ generated intermediates) is compared with that where the relevant intermediates are used as symmetrical preformed and/or isolated precursors for the ordered polymers.
