Polymer Backbone Editing with Cyclopropenes via Olefin Metathesis.

ABSTRACT: The limited ability to recycle or upcycle many commodity polymers with all carbon backbones poses a significant challenge to polymer chemists and society as a whole. In this work, sterically hindered cyclopropenes (CPEs) are used to promote ring-opening cross metathesis reactions with alkene-containing polymers to upgrade the original materials into functional copolymers through a formal backbone editing process. This polymer backbone editing process was able to achieve high conversion of the CPEs (>90%) and maintain reasonable postediting molecular weights (>22 kDa). The method was applied to different CPEs and olefin-containing polymers, resulting in changes in the chemical and thermal properties of the resulting copolymer materials. This work advances avenues for po
