Abstract

Polyamides are prepared by polycondensation of a) a diamine of the dicycane type, b) a polyamide-forming dicarboxylic acid which comprises from 85 to 100 mol % of isophthalic acid and optionally terephthalic acid, and c) an omega -amino acid or a lactam thereof having more than 9 carbon atoms or an aliphatic diamine/dicarboxylic acid salt or mixture (in each case in a molar ratio of 1:1), in particular of a) (4,4'-diamino-3,3'-dimethyldicyclohexyl) methane, b) isophthalic/terephthalic acid (95:5 mol) and c) laurolactam while observing the conditions defined in the Claim. The resultant copolyamides are glass-clear (transparent), have excellent dimensional stability and have excellent stability to boiling water.
