Thermoplastic Toughening of a Semiaromatic Polyamide with an Amino-telechelic Polyethylene Open
Semiaromatic polyamides are used for metal replacement in advanced engineering applications to reduce weight and improve efficiency, but their range of application is limited by their inherent lack of ductility and toughness. Here, we comb…

Semiaromatic Polyamides with Re-Entrant Chain Folding Templated by “U-Turn” Repeat Units Open
Biopolymers often show deterministic chain folding templated by repeat unit sequences whose conformations are locked in by intramolecular interactions. In this work, we have used repeat units based on rigid anthracene or acridine scaffolds…
