| titleOfInvention | Process for preparing polyarylene ether ketone |
| abstract | The present inventionn n n a) reacting an aromatic dihalogen compound with a bisphenol, reacting a halophenol alone, or reacting an aromatic dihalogen compound in the presence of at least one of a carbonate or hydrogen carbonate of an alkali metal and an alkaline earth metal in a high boiling aprotic solvent Reacting with bisphenol and further halophenol to obtain a polyarylene ether ketone,n n n b) pre-extracting the solidified reaction mixture while simultaneously wet grinding;n n n c) extracting and filtering the wet milled product in a pressure suction filter, andn n n d) drying the extracted product; and a method for producing a polyarylene ether ketone.n n n This combination allows for improved workup of the reaction mixture.n n n Polyarylene ether ketones, work up |
