Abstract
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 and significantly increased Tg, while maintaining high Tm, Tc and good mechanical properties, relative to analogous polyamides free of the cycloaliphatic monomer and PA6,T based polyamides copolymerized with either or both of isophthalic acid and adipic acid.
