Abstract: A milling process for the preparation of fine-particled polyarylene ether ketone comprises milling a porous polyarylene ether ketone having a BET surface area of more than 1 m2/g.

Abstract: A transparent component, which comprises the following subcomponents: I. an outer layer composed of a polyamide moulding composition, which comprises the following constituents: a) from 50 to 100 parts by weight of polyamide, which can be prepared from the following monomers: ?) from 70 to 100 mol % of diamine, selected from m-xylylenediamine, p-xylylenediamine and mixtures thereof, ?) from 0 to 30 mol % of other diamines having from 6 to 14 carbon atoms, where the mol % data here are based on the entirety of diamine, and also ?) from 70 to 100 mol % of aliphatic dicarboxylic acids having from 10 to 18 carbon atoms and ?) from 0 to 30 mol % of other dicarboxylic acids having from 6 to 9 carbon atoms, where the mol % data here are based on the entirety of dicarboxylic acid; b) from 0 to 50 parts by weight of another polyamide, where the parts by weight of a) and b) give a total of 100, II.

Abstract: A process for preparing a polyarylene ether ketone comprises the following process steps: a) reaction of an aromatic dihalogen compound with a bisphenol and/or a halophenol in the presence of alkali metal and/or alkaline earth metal carbonate or hydrogencarbonate in a high-boiling aprotic solvent to give a polyarylene ether ketone, b) wet comminution and simultaneous preextraction of the solidified reaction mixture, c) extraction and filtration of the wet-comminuted product in a pressure suction filter and d) drying of the extracted product. This combination enables improved workup of the reaction mixture.

Abstract: A decorative film having an outer layer containing a polyamide composition with the following components: a) from 50 to 100 parts by weight of polyamide prepared from: ?) from 70 to 100 mol % of diamine selected from m-xylylenediamine, p-xylylenediamine and mixtures thereof, ?) from 0 to 30 mol % of other diamines having from 6 to 14 carbon atoms, and ?) from 70 to 100 mol % of aliphatic dicarboxylic acids having from 10 to 18 carbon atoms and ?) from 0 to 30 mol % of other dicarboxylic acids having from 6 to 9 carbon atoms, and b) from 0 to 50 parts by weight of another polyamide, where a) and b) total 100, having good chemicals resistance, good stress cracking resistance, improved scratch resistance, and improved gloss.

Abstract: A polymer powder containing polyarylene ether ketone and having a BET surface area of from 1 to 60 m2/g is suitable for use in a layer-by-layer process in which regions of a powder layer are selectively melted via introduction of electromagnetic energy.
