摘要:
Thermosetting resins and thermosetting composites comprising the thermosetting resins are hot-formable. The compositions result from contacting at least one thermosetting resin precursor with at least one hardener selected from acid anhydrides in the presence of at least one transesterification catalyst. The thermosetting resin precursor includes hydroxyl functions and/or epoxy groups, and optionally ester functions, and the total molar quantity of the transesterification catalyst is between 5 and 25% of the total molar quantity of hydroxyl and epoxy contained in the thermosetting resin precursor. Methods for manufacturing articles comprising the thermosetting resins and methods for recycling the thermosetting resins are also disclosed.
