The invention provides poly(arylene ether ketone/sulfone) containing dynamic covalent bonds, and a polymer foam material prepared by carbon dioxide foaming using the polymer as matrix resin. Dynamic crosslinking structures are introduced into the molecular chains of poly(arylene ether ketone/sulfone), which greatly improves the mechanical properties of the foam material while retaining the intrinsic thermoplastic processability of the resin.
