Post‐functionalization of a ROMP polymer backbone via radical thiol‐ene coupling chemistry

The radical thiol-ene reaction is used to modify the backbone of a common ROMP-prepared homopolymer. Hydrothiolation is successful in most instances in facilitating the ready introduction of a range of functionality including OH, pyrrole, alkyl, ester, and POSS species while still retaining the well-defined characteristics of the parent polymer.
