Beschreibung
Zusammenfassung:	Composition comprises (in wt.%) (a) solidified lactam melts with at least one polymeric carbodiimide (0.1-5) and/or at least one uretdione, (b) solidified lactam melts with catalyst (0.2-5) comprising lactam-magnesium-halide, alkali-alumino-dilactamate, alkali and/or alkaline earth-lactamate, and/or (c) solidified lactam melts with the catalyst, carbodiimide and/or uretdione. Independent claims are also included for: (1) solidified lactam melts comprising the above catalyst, -carbodiimide and/or -uretdione, obtainable by mixing at least one melt made of caprolactam, carbodiimide and/or uretdione, and at least one melt made of caprolactam and catalyst, at 70-120[deg] C for 1-60 seconds, and cooling; and (2) producing cast polyamides by polymerization of at least one component of the above composition in the mold at 100-160[deg] C.
