Abstract: A thermoplastic component may include a matrix component (A) and a filler component (B). The matrix component (A) may include a polyetheretherketone and the filler component (B) may include inorganic particles and carbon-containing particles. The overall composition may include equal or different portions, as filler component (B), of hydrophobic silicon dioxide, carbon fibres, titanium dioxide particles, graphite particles, and a particulate lubricant selected from divalent metallic sulfides and alkaline earth metal sulfates.

Abstract: A molding compound for joining two moldings each made of a PA11 and/or PA12 molding compound contains at least 50% by weight of a polyamide component so chosen that it is preparable from linear aliphatic diamines and dicarboxylic acids and/or lactams or ?-aminocarboxylic acids, there being 11 to 12 carbon atoms present per carboxamide group in the repeating units, and, furthermore, this polyamide component containing not more than 80% by weight of either one of the polyamides PA11 and PA12. With this compound a firm weld is obtained both to a PA11 molding and to a PA12 molding.

Abstract: A process for preparing a polyarylene ether ketone, comprising: a) reacting an aromatic dihalogen compound with a bisphenol and/or a halophenol in the presence of alkali metal carbonate and/or alkaline earth metal carbonate in a high-boiling aprotic solvent to give a polyarylene ether ketone, b) wet-comminuting the solidified reaction mixture in the presence of water, c) washing with an organic solvent, d) washing with water and e) drying the washed product, wherein the wet-comminuted reaction mixture is fed to the two-stage washing with a residual moisture content of at least 1% by weight, which process leads to distinctly reduced residual contents of salts and reaction solvents.

Abstract: A process for preparing a polyarylene ether ketone by reacting an aromatic dihalogen compound with a bisphenol in the presence of alkali metal carbonate and/or alkaline earth metal carbonate 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.
