A remoldable bismaleimide resin and application thereof. The preparation method includes blending 2-allylphenyl glycidyl ether and terephthalic acid in acetonitrile, carrying out an esterification reaction under the condition of quaternary ammonium salt as a catalyst to obtain bis(3-(2-allylphenoxy)-2-hydroxypropyl) terephthalate containing a reversible dynamic group; then uniformly mixing bis(3-(2-allylphenoxy)-2-hydroxypropyl) terephthalate and bismaleimide, curing to obtain the re-moldable bismaleimide resin. The prepared re-moldable bismaleimide resin not only has excellent heat resistance and mechanical properties, but also can be remolded under hot pressing conditions. The preparation method of the re-moldable bismaleimide resin has the advantages of wide raw material sources and simple process, and has a wide application prospect in the fields of aerospace, transportation, electronic information, new energy, insulated electrical industry and the like.
