Precise Carboxylic Acid-Functionalized Polyesters in Reprocessable Vitrimers.

ABSTRACT: Thermosets are valued for their exceptional dimensional stability, mechanical properties, and resistance to creep and chemicals. Their permanent molecular structures limit reshaping, reprocessing, and recycling. Incorporating exchangeable chemical bonds into cross-linked polymer networks provides materials with thermoset-like properties that are also reprocessable. Here, ring-opening copolymerization (ROCOP) of unpurified, commercially available epoxides and succinic anhydride is employed to synthesize well-defined, low molecular weight polyesters with controlled functionalization. Polymer networks are then formed through the catalyzed reaction of these copolymers with the epoxy-containing cross-linker diglycidyl ether of bisphenol A. Catalyst mixtures of zinc bis(2-ethylhexanoate) and 1,8
