Abstract
The transparent co-polyamides according to the invention are obtained by co-polycondensation of mixtures of terephthalic acid, or of an amide-forming derivative thereof, and a diamine of the formula I <IMAGE> in which R1 and R2 are each cycloalkyl which has 4-12 C atoms and which can be substituted by alkyl, (a) with an aliphatic amino acid, for example 10 to 20% by weight of epsilon - aminocaproic acid or caprolactam or b) with an aliphatic diacid-diamine combination, for example 10 to 20% by weight of an essentially stoichiometric mixture of adipic acid and hexamethylene-diamine or of the AH salt. The polycondensation reaction is performed by known methods, preferably by melt condensation. The resulting polyamides are transparent and are resistant to boiling. They show only a slight absorption of water and are stable to hydrolysis. They can be processed for example by the injection-moulding process and by extrusion into the form of moulded articles.
