Abstract

Monomers possessing two functionalities suitable for polymerization are intuitively associated to crosslinked macromolecules and their multiple applications. Suitably designed difunctional monomers can in fact be subjected to cyclopolymerization processes to form linear, soluble macromolecules. These processes achieve cyclic moieties of variable ring size which are embedded within the polymer backbone, affording peculiar properties of the resulting macromolecules, including recognition. The two functionalities are covalently linked by a “tether”, which can be appropriately designed in order to “imprint” elements of chemical information into the polymer backbone during the synthesis, and, in some cases, be removed by post polymerization reactions. The two functionalities can possess identical or even very different reactivities towards free radical polymerization; in the latter case, consequences and outcomes related to the sequence-controlled, precision synthesis of macromolecules have been recently demonstrated. In this Feature Article, we account about such recent developments related to the use of cyclopolymerization for sequence-controlled polymerization.
