NBR/PA6 blends were prepared at the melt state and with the use of masterbatches. Compatibilization with NBR-oxazoline was tested with the aim of enhancing the blend performance and to obtain more appropriated morphology. The effect of compatibilizer content was studied through the characterization of blend mechanical properties, creep behavior, swelling, PA6 phase crystallinity, morphology, and rheological properties, including pressure-volume-temperature behavior. The results show a more significant elastomeric behavior for blends with 5 and 7 phr of compatibilizer, with deleterious effects for higher content. The migration of compatibilizer into elastomeric phase was documented by electronic microscopy, and corroborated by an increase in free volume of the samples.

Thermally stable thermoplastic elastomer nanocomposites based on polyamide 6 (PA6), acrylonitrile butadiene rubber (NBR), and halloysite nanotubes (HNTs) were dynamically vulcanized, and their nonisothermal decomposition kinetics were examined. The Friedman, Kissinger–Akahira–Sunose (KAS), Ozawa–Wall–Flynn (FWO), and modified Coats–Redfern (m‐CR) isoconversional models were used to obtain information about the kinetics of the thermal decomposition of PA6–NBR–HNTs in terms of the activation energy per partial mass loss monitored through thermogravimetric analyses performed at different heating rates. An erratic trend was due to the Friedman model, especially for systems having higher HNT loadings, whereas the KAS, FWO, and m‐CR models revealed very similar meaningful thermal decomposition kinetics. A relatively high activation energy corroborating a reliable thermal stability was obtained by the addition of HNTs to PA6–NBR, and the resistance against decomposition was higher for systems containing more HNT. This signified the role of the HNTs as thermal stability modifiers. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47483.
