Abstract: Transparent polyamides are produced by polycondensing mixtures of isomeric amino-methyl amino-propyl norbornanes or mixtures thereof with aliphatic, cycloaliphatic, aromatic or aromatic aliphatic diamines and aliphatic, cycloaliphatic or aromatic dicarboxylic acids or mixtures of the said dicarboxylic acids with amino carboxylic acids.

Abstract: There are disclosed and claimed novel polyamides having improved properties such as high transparency and second order transition temperatures in combination with good mechanical and electrical properties at relatively high temperatures. These polyamides are derived from bis-aminomethyl-norbonanes and aliphatic or cycloaliphatic or aromatic or aromaticaliphatic diamines, aliphatic or aromatic dicarboxylic acids. and amino carboxylic acids.
