Zusammenfassung:Described herein are polyamides (PA) incorporating a cycloaliphatic monomer containing a cyclohexyl group. It was surprisingly discovered that by incorporating the cycloaliphatic monomer containing a cyclohexyl group, the resulting polyamides (PA) had significantly reduced water absorption, while maintaining good mechanical properties, relative to both analogous polyamides free of the cycloaliphatic monomer as well as relative to both PA6,T based polyamides copolymerized with either or both of isophthalic acid and adipic acid.
