THERMOPLASTICALLY DEFORMABLE IMPACT RESISTANT POLYAMIDE ALLOY

A thermoplastic mouldable, impact-resistant, polyamide alloy comprises (a) at least 98% by weight of an amorphous copolyamide derived from an optionally alkyl-substituted hexamethylenediamine, a bis(4-aminocyclohexyl) C1-4 alkane substituted adjacent to the amino groups, and a dicarboxylic acid, and (b) up to 80% by weight of a modified copolyolefine. Moulded bodies obtained from such alloys exhibit high rigidity with outstanding impact resistance over a broad range of temperature, very low water uptake, very high dimensional stability and low permeability to oxygen as well as high shape retention on heating and, on account of their relatively low melt viscosity, are very suitable for processing in injection moulding and extrusion procedures, particularly for the preparation of e.g. thin-walled or large surface area parts such as claddings, films, etc.
