    摘要： The present invention relates to a method for producing a polyamide (P) via the reaction of a mixture (M) which contains 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)). In addition, the present invention relates to the mixture (M) and the use of an oxazolidine derivative in order to increase the crystallisation rate of a polyamide (P). The present invention also relates to the use of an oxazolidine derivative in a polyamide (P) in order to produce a moulded body made from the polyamide (P) so as to reduce the time for removing the moulded body from the mould, and to the use of an oxazolidine derivative in order to remove water from a reaction mixture (RM).

    摘要： The present invention relates to a method for producing a polyamide (P) by mixing a first mixture (M1), which contains at least one lactam and at least one catalyst, with a second mixture (M2), which contains at least one lactam, at least one activator and at least one amine, to obtain a polymerizable mixture (pM), and subsequent polymerization of the polymerizable mixture (pM), to obtain the polyamide (P). The present invention also relates to a polyamide (P), which can be produced according to the method according to the invention, and to shaped bodies made from the polyamide (P).
