ABSTRACT:
A thermoplastic polyamide comprising a copolyamide and a modified copolyolefin. The copolyamide is the reaction product of a hexamethylene diamine, which may be substituted with one or more alkyl groups, and a his (4-aminocyclohexyl) alkane which is substituted adjacent to the amino groups, and a dicarboxylic acid.
Molded bodies made therefrom have high rigidity, excellent impact resistance over a broad temperature range, low water uptake, high dimensional stability, low permeability to oxygen, and high shape retention on heating. They are particularly suitable for injection molding and extrusion, especially for the preparation of thin walled or large surface area shapes.
