ABSTRACT:
The partially crystalline polyamides according to the invention are obtained by reacting terephthalic acid, or an amide-forming derivative thereof, with a diamine of the formula ##STR1## in which R.sub.1 and R.sub.2 singly or together are organic radicals. The reaction mixture can also contain up to 30% by weight of other amide-forming substances (aminocarboxylic acids or lactams, or mixtures of dicarboxylic acids and diamines), provided the formation of the partial crystallinity of the resulting polyamides is retained. The polyamides are suitable for producing moulded products of the most varied types. They are particularly applicable for producing filaments and fibres.
