Abstract:Architecture
underlies the thermomechanical properties of polymers.
Yet, few strategies are available to tune a polymer’s architecture
after it is prepared without altering its chemical composition. The
ability to edit the architecture of a polymer would dramatically expand
the accessible architecture-property space of polymeric materials.
Herein, we disclose a backbone rearrangement approach to tune the
short-chain branching of polymers. Specifically, we demonstrate that
palladium(II)-catalyzed [3,3]-sigmatro… Show more
