| titleOfInvention | A process for producing an improved polyether ketone ketone and polyether ketone ketone thereof |
| abstract | The present invention relates to an improved method for producing a polyether ketone ketone and a polyether ketone ketone prepared thereby, more specifically, using 1,4-diphenyl benzene as a reaction monomer, or 1,4-diphenyl benzene Using a mixture of and diphenyl oxide, the crystallization rate of the polymerization reaction is increased to improve the injection molding processability. In addition, it relates to an improved polyether ketone ketone production method by adding a capping agent to a monomer during polymerization, thereby improving the flowability of the resin, and to a polyether ketone ketone produced thereby. According to the present invention, (a) at least one selected from 1,4-diphenoxy benzene and 1,4-bis(4-phenoxybenzoyl)benzene (EKKE) in the reactor, terephthaloyl chloride (TPC), Preparing a reaction solution by dissolving in isophthaloyl chloride (IPC) and a liquid reaction medium at the same time; (b) lowering the temperature of the reaction solution and then adding a catalyst; (c) after the catalyst is introduced, directly blowing and stirring an inert gas into the reaction solution; And (d) adding the first capping agent (capping agent) after the inert gas input; provides a method for producing a polyether ketone ketone comprising a. Therefore, it is effective to improve the injection molding processability by increasing the crystallization rate of the polymerization reaction and to improve the flowability of the resin. |
