摘要： The invention relates to a flame-resistant polyamide as a reaction product of a lactam, in particular of ε-caprolactam and/or laurolactam, and optionally containing other components. In the main chain thereof, said frame-resistant polyamide contains, in addition to the polyamide structural units, phosphor-modified structural units and optionally aminopiperidine groups. The polyamide has a relative viscosity of at least 1.7, in particular at least 1.9 (measured according to DIN 51562). The polyamide is suitable for producing moulded bodies, in particular films, components and yarns, in particular monofilament or multifilament yarns and staple fibre yarns, preferably as part of an extrusion method. The invention also relates to a method which is particularly suitable for producing said flame-resistant polyamide. During the polycondensation of the respective lactam, phosphor-containing compounds are copolycondensed and heat-stabilised to obtain a frame-resistant polyamide.
