SULFONATED POLYAMIDE POLYMER BLENDS AND CORRESPONDING ARTICLES
Publication/Patent Number: US2020247992A1 Publication Date: 2020-08-06 Application Number: 16/758,409 Filing Date: 2018-10-10 Inventor: Davis, Raleigh L.   Gautam, Keshav S.   Jeol st xe9 phane   Assignee: SOLVAY SPECIALTY POLYMERS USA, LLC   IPC: C08L77/04 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.
