The invention relates to a liquid initiator for carrying out anionic lactam polymerization. The liquid initiator contains a conversion product of isocyanate (1) with a protic compound (P) and a base (B) in an aprotic solvation agent (S).

Liquid initiator for carrying out anionic lactam polymerization in an accelerated manner, method for the production thereof and its use

The invention relates to a liquid initiator to be used in anionic lactam polymerization. Said liquid initiator contains a reaction product of carbodiimide with a protic compound and a base in an aprotic solvation agent.

Liquid initiator for accelerating the progress of the anionic lactam polymerization, method for producing the same and the use thereof

The invention relates to a polyamide with low viscosity degradation after remelting which can be produced by anionic polymerization of lactam in the presence of alkaline catalysts and if necessary activators and the method for production of the polyamide. The invention relates furthermore to a method for reprocessing anionically produced polyamide.

Anionically produced polyamide and method for the production thereof and also a method for reprocessing polyamide

A method for the production and use of a catalytically-acting liquid system is offered, which has no or only a small proportion of free lactam, and which is of low viscosity and good storage stability and which directly initiates the anionic lactam polymerization.

Method for producing a liquid system for lactam polymerization

The invention relates to a thermoplastically processible molding material with a two-phase matrix of a partially aromatic copolyamide and an aliphatic polyamide or copolyamide containing permanently magnetic or magnetizable fillers, as well as to a method for producing this molding material and using it for producing molded parts.
