Partially Bio‐Based Reactive Poly(Arylene Ether Ketone)s With Tunable Carboxyl Contents for Toughening Epoxy Resin
Epoxy thermosets combine high strength, thermal stability, and chemical resistance, but their densely crosslinked networks also make them susceptible to brittle fracture. Here, partially bio‐based reactive poly(arylene ether ketone) copolymers (PEK‐DA) containing different amounts of pendant carboxyl groups were sy...
