STABILIZATION OF POLYAMIDE WITH COPPER-BASED METAL ORGANIC FRAMEWORKS

摘要

The invention relates to a method for manufacturing of a stabilized polyamide-containing composition, which contains at least 20% by weight of polyamide, which comprises the steps of incorporating of a metal organic framework, which is a copper-based metal organic framework comprising metal ions, which are copper(II)-ions, and a C6-C24 aromatic hydrocarbon, which is substituted with at least two carboxylate groups, wherein two of the at least two carboxylate groups are forming coordinative bonds to the metal ions, into a polyamide-containing composition, which contains at least 20% by weight of polyamide, to obtain a mixture for molding, which contains at least 20% by weight of polyamide; and heating of the obtained mixture for molding comprising the polyamide-containing composition and the metal organic framework to a temperature between 170° C. and 380° C.
