K-18023/A/CGM 363 Soluble polyarylene ether ketones Abstract of the Disclosure Polyarylene ether ketones which are soluble in halogenated hydrocarbons and have a reduced viscosity of 0.1 to 2.0 dl/g, measured at 25°C using a 1 % solution of the polymer in N-methylpyrrolidone (NMP), which polyarylene ether ketones contain, based on the total number of structural units present in the polyarylene ether ketone resin, 1-100 mol % of a recurring structural unit of formula I or II Image (I), Image (II) and 99-0 mol % of a recurring structural unit of formula III Image (III) wherein R1 is alkyl, alkoxy, aryl, alkenyl or halogen, and m is 0 or an integer from 1-4, R2 is C1-C4alkyl, C1-C4alkoxy, C6-C12aryl or halogen, and n is 0 or an integer from 1-4, Ar1 is a divalent radical of a bisphenol compound and Ar2 is a divalent radical of an activated dihalo compound which is able to enter into a nucleophilic exchange reaction. These polyarylene ethers can be readily processed from the solution and are suitable for modifying matrix resins.
