Abstract:
The invention relates to a polyamide comprising units derived from: A. a diamine comprising in its structure at least one cyclohexane fragment according to Structure I, in which the substituents are in the 1,4-trans-position (Structure I), with n a positive integer of at least 1, and the proviso that when n is 2 or higher the cyclohexane rings are connected to each other through the 1,4-trans position, B. an aliphatic dicarboxylic acid with at least 13 carbon atoms and optionally comprising units derived from: C. one or more aliphatic dicarboxylic acids other than B, D. one or more diamines other than A, E. one or more monofunctional carboxylic acids or monofunctional amines, F. one or more polyfunctional monomers comprising carboxylic acid and/or amine groups, G. one or more lactams or corresponding amino acids. The invention further relates to a composition comprising such a polyamide and its uses.
