Rheological Characterisation of Poly(FLP) Networks

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.
