Abstract Polyimide materials with high mechanical strength are widely used in various fields, but pose certain challenges achieving sustainable material utilization. A poly(imide‐imide) vitrimer (ADTA) based on multiple dynamic covalent bonds (imide, imine, and disulfide bonds) was constructed by preparing vanillin difunctionalized derivatives (DVA) for aldolamine condensation reactions bis‐amine monomers (ATFA) tris(2‐aminoethyl) amines (TAEA) imide structures. The ADTA has good 5% thermal stability T d (278.87°C), energy storage modulus E (2421.26 MPa), fast relaxation time (36.39 s). properties of the enhanced more stable alicyclic structure structure. also demonstrated excellent solvent resistance self‐healing properties. This study provides a new option development utilization polyimide materials.
