    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing polyarylene ether ketone with improved molar mass control and regulation.
    SOLUTION: The process for preparing the polyarylene ether ketone by reacting an aromatic dihalogen compound with a bisphenol in the presence of alkali metal and/or alkaline earth metal carbonate or hydrocarbonate in a high-boiling solvent, where the molar mass is established by, in the course of the polycondensation, bringing the molar mass to a target value by again adding a bisphenol or an aromatic dihalogen compound to the reaction.

    Abstract: A process for preparing a polyarylene ether ketone is provided to manage and control the molar mass better, thereby setting the desired molar mass in a controlled manner. A process for preparing a polyarylene ether ketone comprises reacting an aromatic dihalogen compound with a bisphenol in the presence of an alkali metal carbonate and/or an alkaline earth metal carbonate in a high-boiling point solvent, wherein the molar mass in the reaction is established by bringing the molar mass to a desired value via further addition of a bisphenol or an organic halogen compound to the reaction in the course of polycondensation. Preferably, the dihalogen compound used in polycondensation is 4,4'-difluorobenzophenone, and the bisphenol used in polycondensation is hydroquinone.

    Abstract: PROBLEM TO BE SOLVED: To obtain an easily flowable transparent polyamide molding material whose mechanical properties have not been adversely affected with additives remarkably. SOLUTION: This molding material comprises (I) 50-90 pts.mass transparent polyamide and (II) 1-50 pts.mass [provided that the sum of (I) and (II) pts.mass is 100] graft copolymer to be produced by using, as the monomers, (a) 0.5-25 mass% (based on the graft copolymer) branched polyamide having at least 4 nitrogen atoms and a number average molecular weight Mn of 146 g/mol and (b) a polyamide-forming monomer selected from an equimolar combination of a lactam and an ω-aminocaboxylic acid and/or a diamine and a dicarboxylic acid.
