Abstract
Colorless, amorphous, transparent copolyamides, their blends or alloys, and molded articles with high alternate bending strengths that can be produced from them. The copolyamides are preferably made of cycloaliphatic diamines combined with aliphatic dicarboxylic acids and small amounts of aromatic dicarboxylic acids. The copolyamides exhibit high strength, high rigidity, high heat distortion, and good solvent resistance.
