Beschreibung
Zusammenfassung:	Polymer powder (I), useful in layerwise working procedure, where selective ranges of the respective powder layer is melted by electromagnetic energy, comprises polyarylene ether ketone (PAEK) powder and has a BET surface of 1-60 m 2>/g. Independent claims are also included for the preparation of (I); #a method for preparing molded articles, by a layerwise working procedure, comprising melting the selective ranges of the respective polymer powder layer by adding electromagnetic energy; #molded articles, prepared by the method, comprising a polymer of polyarylene ether ketone.
