ABSTRACT:
A thermoplastic polyamide comprising a copolyamide which is the reaction product of a hexamethylene diamine unsubstituted or substituted with at least one alkyl group, and a bis(4-aminocyclohexyl) alkane which is substituted adjacent to the amino groups, and a dicarboxylic acid. Molded bodies made therefrom have high rigidity and tensile strength over a broad temperature range, low water uptake, high dimensional stability, low permeability to oxygen, and high distortion temperatures. They are particularly suitable for injection molding and extrusion particularly when they are modified to improved impact strength, especially for the preparation of thin walled or large surface area shapes.
