Congrats to Utku and Meng for their new Macromolecules paper! This work further investigates the rheological properties of our novel polymeric Frustrated Lewis Pairs.
The original styrene-FLP copolymers were studied, as were newly synthesised FLP-MMA copolymers. The networks formed upon addition of a DEAD linker behave as non-covalent supramolecular assemblies with a high temperature dependence. Increasing crosslink density resulted in a more solid-like material, as did the switch to a more flexible MMA backbone as a result of more facile chain rearrangement.
