Abstract
Described herein are polyamide polymer blends including a sulfonated polyamide polymer, an aromatic polyamide polymer and a reinforcing filler. Optionally, the polyamide polymer blend includes an additive. It was surprisingly discovered that blends including a sulfonated polyamide polymer in addition to an aromatic polyamide polymer had increased mechanical performance, relative to corresponding polyamide polymer blends having a non-sulfonated polyamide polymer. Furthermore, it was also surprisingly discovered that, when the sulfonated polyamide polymer included a sodium counter-ion, the mechanical performance of the polyamide polymer blend was further enhanced, relative to corresponding polyamide polymer blends having a sulfonated polyamide polymer including a lithium counter-ion in place of a sodium counter-ion. Due, at least in part, to the increased mechanical performance, the polyamide polymer blends can be desirably incorporated into structural components, which generally benefit from higher mechanical performance.
