Abstract: A process for the production of a polyamide is disclosed. The process for production of a polyamide (P) comprises mixing a first mixture (M1), which comprises at least one lactam and at least one catalyst, with a second mixture (M2), which comprises at least one lactam, at least one activator and at least one amine, to give a polymerizable mixture (pM) and then polymerization of the polymerizable mixture (pM) to give the polyamide (P). A polyamide (P) obtainable by the process of the invention is also disclosed, as well as moldings made of the polyamide (P).

Abstract: Provided herein is a process for producing a polyamide (P) by reaction of a mixture (M) including at least one lactam (component (A)), at least one catalyst (component (B)), at least one activator (component (C)), and at least one oxazolidine derivative (component (D)). Further provided herein is the mixture (M) and the use of an oxazolidine derivative for increasing the crystallization rate of a polyamide (P). Also provided herein is the use of an oxazolidine derivative in a polyamide (P) for producing a molded article from the polyamide (P) for reducing the demolding time of the molded article and the use of an oxazolidine derivative for removing water from a reaction mixture (RM).
