    摘要: Stabilized shaped articles of polyamides are prepared in a simple manner, using a copper-I halide and a molar excess of an alkali or alkaline earth metal halide, by mixing copper(I)-halide and alkali or alkaline earth metal halide with caprolactum, polymerizing the mixture, granulating the melt of the stabilizer concentrate and processing the granules together with the granulated polyamide which is to be stabilized, to give shaped articles.
