Abstract
Abstract
Thermoplastic elastomer nanocomposites (TPE nanocomposites) based on PA6/ NBR/Cloisite 30B were prepared through a direct melt mixing process in an internal mixer. The effects of NBR content (10, 30 and 50 wt.%) and nanoclay loading (3, 5 and 7 wt.%) on morphology and mechanical properties of the nanocomposites have been studied and compared with unfilled PA6/NBR blends as well. The TPE nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), differential scanning calorimeter (DSC) and mechanical properties. XRD results suggested that the nanoclay is exfoliated into the TPE nanocomposite matrix. TEM image of the PA6/NBR/nanoclay composite showed partial exfoliated structure of silicate layers dispersed through the both NBR and PA6 phases. The SEM photomicrograph of PA6/NBR nanocomposite showed an increasing of the rubber particles size in comparison with unfilled PA6/NBR TPE. By presence of nanoclay, improved modulus of the prepared TPE nanocomposites was achieved. DSC studies showed that loading of the nanoclay reduced the degree of crystallinity of the nanocomposite samples.

Abstract
Elastômeros termoplásticos vulcanizados, TPVs, à base de co-poliamida (PA6,6-6) e borracha nitrílica (NBR), foram preparados por vulcanização dinâmica em câmara de mistura a partir de um sistemas de vulcanização tendo como componente principal o peróxido de dicumila e os coagentes bismaleimida e enxofre. Variando-se a proporção dos componentes, estudou-se a influência do enxofre sobre as propriedades mecânicas e deformação permanente à compressão. A morfologia foi determinada por análise de microscopia eletrônica de varredura. Todos os TPVs apresentam propriedades mecânicas superiores à blenda PA/NBR correspondente. TPVs com domínios elastoméricos da ordem de 5 µm foram obtidos com o sistema de reticulação constituído de peróxido de dicumila/bismaleimida/enxofre (DCP/BMI/S) na proporção de 2,4/0,4/0,7 php, independentemente da forma de apresentação da NBR (compacta ou pó). Estes materiais apresentaram excelente desempenho mecânico alcançando-se tensões de ruptura da ordem de 20 MPa. A presença do enxofre conferiu propriedades mecânicas particulares aos TPVs. Para todos os sistemas de reticulação, os TPVs apresentaram boa resistência química em solventes apolares (iso-octano e óleo 20W50), atribuída à natureza química do par PA/NBR, e valores similares para a deformação permanente à compressão.
