Simplified Production of Nylon-6

A process for producing polyamides from the corresponding monomers and/or prepolymers comprises the steps of (a) reacting the monomers and/or prepolymers and optionally further components under polyamide-forming reaction conditions to form polyamide, (b) treating the polyamide obtained in step (a) i...

Beschreibung
Zusammenfassung:	A process for producing polyamides from the corresponding monomers and/or prepolymers comprises the steps of (a) reacting the monomers and/or prepolymers and optionally further components under polyamide-forming reaction conditions to form polyamide, (b) treating the polyamide obtained in step (a) in a kneader above the melting temperature of the polyamide, (c) further processing the polyamide from step (b) into pellet, film, fiber or moldings, preferably pelletizing the polyamide, (d) extracting some or all unconverted monomers and any product dimers and oligomers and also optionally further components from the polyamide and/or drying the polyamide.
