Polyaryletherketone oligomer with side group containing carboxyl, thermosetting shape memory polyaryletherketone and preparation method of thermosetting shape memory polyaryletherketone

The invention provides a polyaryletherketone oligomer with a side group containing carboxyl, thermosetting shape memory polyaryletherketone and a preparation method of the thermosetting shape memory polyaryletherketone, and belongs to the technical field of high-molecular polymers. 4, 4-difluorobenzophenone, hexafluorobisphenol A and diphenolic acid are used as reaction monomers, carboxyl can be introduced into a polyaryletherketone oligomer structure, and the polyaryletherketone oligomer with the side group containing carboxyl is obtained. The obtained polyaryletherketone oligomer has good solubility in a polar solvent, can realize simple and rapid prototyping of polyaryletherketone, overcomes the defects of existing polyaryletherketone prototyping manufacturing, and expands the application range of polyaryletherketone. The polyaryletherketone oligomer with the side group containing carboxyl is used as a raw material and matched with cyanate ester as a cross-linking agent, simple, convenient and rapid curing
