description The invention provides a phenolphthalein-based polyaryletherketone polymer and an end capping method, and belongs to the technical field of polyaryletherketone polymer synthesis. The invention provides an end-capping method of phenolphthalein polyaryletherketone through nucleophilic condensation reaction between a phenol end group and active aryl monohalide or between a halogen end group and monophenol. The method not only can introduce the end-capping reagent in the polymerization process, but also can perform end capping on a specific end group polymer or an untreated solution to obtain the end-capped polyaryletherketone resin with higher stability, and the specific concentration viscosity of the polymer can be adjusted by selecting the end-capping reagent, regulating the adding amount and regulating the process, so that the stability of the polyaryletherketone resin is improved, and the service life of the polyaryletherketone resin is prolonged. The harsh requirements of extrusion, injection molding and ot
