Abstract

There is disclosed a process for the preparation of novel transparent polyamides with improved properties. These polyamides are obtained by polycondensing 1,3-bis-(amino-methyl)-cyclohexane, which can be partly substituted by the 1,4-derivative, at least one aromatic dicarboxylic acid and at least one amino-carboxylic acid or the lactam thereof with at least one aliphatic straight chain or branched diamine or/and at least one aliphatic straight chain or branched dicarboxylic acid.
