Soluble polyarylenetherketones.

摘要

Polyarylene ether ketones which are soluble in halogenated hydrocarbons and have a reduced viscosity of from 0.1 to 2.0 dl/g, measured at 25 DEG C on a 1% strength solution in N-methylpyrrolidone (NMP) and contain, based on the total amount of structural units present in the polyarylene ether ketone resin, 1-100 mol% of a recurring structural unit of the formula I or II and 99-0 mol% of a recurring structural unit of the formula III &lsqbstr& O-Ar2-O-Ar1 &rsqbstr& (III), in which R1 is alkyl, alkoxy, aryl, alkenyl or halogen, m is zero or a number from 1 to 4, R2 is C1-C4-alkyl, C1-C4-alkoxy, C6-C12-aryl or halogen, n is zero or a number from 1 to 4, Ar1 is a divalent radical of a diphenolic compound, and Ar2 is a divalent radical of an activated dihalogen compound which is capable of undergoing nucleophilic exchange reactions, can advantageously be processed from solution and are suitable for modifying matrix resins.
