Copolyamides based on polyamide-6,6 (PA-6,6) were prepared by solid-state modification (SSM). Para- and meta-xylylenediamine (PXDA, MXDA resp.) were successfully incorporated into the aliphatic PA-6,6 backbone at 200 and 230 °C under an inert gas flow. In the initial stage of the SSM below the melting temperature of PA-6,6 a decrease of the molecular weight was observed due to chain scission, followed by a built up of the molecular weight and incorporation of the comonomer by post-condensation during the next stage. When the solid-state copolymerization was continued for a sufficiently long time, the starting PA-6,6 molecular weight was regained. The incorporation of the comonomer into the PA-6,6 main chain was confirmed by size exclusion c...
