ELECTRICAL AND ELECTRONIC ARTICLES INCLUDING POLYAMIDE COMPOSITIONS

Described herein are electrical articles comprising a polyamide (PA). As explained in detail below, the polyamide (PA) is a semi-aromatic polyamide derived from the polycondensation of an aliphatic diamine, terephthalic acid, and a bis(aminoalkyl)cyclohexane or a cyclohexanedicarboxylic acid. It was surprisingly discovered that incorporation of the cycloaliphatic diamine bis(aminoalkyl)cyclohexane or the cycloaliphatic dicarboxylic acid cyclohexanedicarboxylic acid into the polyamide provided for polymer compositions (PC) having significantly improved comparative tracking index (“CTI”) retention after heat aging, relative to analogous polyamides derived from only the aliphatic diamine and terephthalic acid. Due at least in part to the improved CTI retention, the polyamides (PA) can be desirably incorporated into articles that, during use, are exposed to elevated temperatures and benefit from high CTI performance.
