| titleOfInvention | Production process of polyether ketone |
| abstract | The invention belongs to the technical field of polymer synthesis, and particularly relates to a production process of polyether ketone. Firstly, adding a monomer and Lewis base into a reaction kettle, and then dropwise adding anhydrous aluminum trichloride dissolved in sulfur dioxide into the reaction kettle. And one part of the added aluminum trichloride is complexed with Lewis base, one part of the added aluminum trichloride is complexed with carbonyl on acyl chloride, and the other part of the added aluminum trichloride plays a role in catalysis, the three reactions are exothermic reactions, the heat promotes the gasification of sulfur dioxide into gas which leaves a reaction system, and the heat absorbed by the gasification counteracts the heat released by adding part of the aluminum trichloride, so that the temperature inside the reaction kettle at the initial stage of the reaction is uniform, and the occurrence of side reactions is reduced. In addition, the monomer is added into the reaction bottle before the reaction is started, the concentration of the monomer is the largest at the beginning of the reaction, a pseudo-dilution state does not exist, the generation of small molecular cyclic polymers is reduced, and the produced polyether ketone has better impact property, better toughness and higher intrinsic viscosity. |
