(57) [Summary] [Reference number] C352 [Purpose] To provide a polyarylene ether ketone soluble in a conventional solvent such as a halogenated hydrocarbon. [Structure] 1 to 100 mol% of the following formula I based on the total number of structural units present in the polyarylene ether ketone resin. Or II [Chemical 2] In represented by the repeating structural units and 99 to 0 mole percent of the formula III: - [O-Ar 2 -O-Ar 1] - characterized in that it comprises a repeating structural unit represented by, soluble in halogenated hydrocarbons When dissolved, N-methylpyrrolidone (NM Polyarylene ether ketone having a reduced viscosity of 0.1 to 2.0 dl / g measured at 25 ° C. in a 1% solution of P). [Effect] The above-mentioned polymer is used for molded articles, films, sheets, coated articles, etc., and is particularly effective for incorporation into a thermoplastic matrix resin due to its solubility. |
