Patent ID: 8871862

Claim:
A molding composition comprising at least 30% by weight, based on the weight of the composition, of a copolyamide, the copolyamide comprising, in reacted form a) 50 to 95 mol % of a first mixture consisting of terephthalic acid and one diamine selected from the group consisting of 1,9-nonanediamine, 1,10-decanediamine, 1,11-undecanediamine and 1,12-dodecanediamine, and b) 5 to 50 mol % of a second mixture consisting of terephthalic acid and at least one diamine selected from the group consisting of 2,2,4-trimethylhexamethylenediamine and 2,4,4-trimethylhexamethylenediamine, where the mol % values are based on the entirety of components a) and b), and at most 5 mol % of units which derive from one or more other monomers selected from the group consisting of an acid other than terephthalic acid, a lactam and an aminocarboxylic acid.
