Abstract

The invention discloses an industrial synthesis method of high-thermal-stability terminated polyaryletherketone resin. The industrial synthesis method of the high-thermal-stability terminated polyaryletherketone resin comprises the following steps: carrying out polymerization reaction by taking a 4,4'-difluorobenzophenone monomer, a 4,4'-dihydroxy benaophenonel monomer and a bisphenol monomer as reaction monomers, taking a high-boiling-point organic solvent as a solvent, taking alkali carbonate as a salt-forming agent and taking an asymmetric aromatic ketone derivative as a terminating agent to obtain a polymerized adhesive liquid; cooling the polymerized adhesive liquid, then crushing the polymerized adhesive liquid into powder, filtering the powder, subsequently boiling the liquid by using an organic solvent and deionized water, washing to remove the solvent and side product salt, drying the liquid to obtain polyaryletherketone resin. According to the industrial synthesis method, alkali metal sodium carbonate is independently taken as a catalyst; an excellent terminating effect is exerted after the terminating agent is added; the system is not depolymerized; the terminated polyaryletherketone resin synthesized by the method has high-temperature thermal stability.
