Resumo: In this work, polyamide 6 (PA6) was toughened with the terpolymer of acrylonitrile-EPDM-styrene (AES), using ethylene-propylene-diene grafted with maleic anhydride (EPDM-MA), as a compatibilizing agent. The blends were prepared in a co-rotational twin-screw extruder and subsequently injection molded. The properties of impact strength, tensile strength and morphology were evaluated. The results indicated expressive increases in the impact strength of the PA6/AES/EPDM-MA blends, compared to the neat PA6. However, the elastic modulus and tensile strength suffered decreases, due to the increased flexibility of the developed blends. The PA6/AES blend compatibilized with 15% of EPDM-MA presented itself as a supertough and ductile material at room temperature. The images obtained by scanning electron microscopy (SEM) indicated that the increase in the EPDM-MA compatibilizer content favored the presence of more refined and well-adhered particles in the PA6 matrix, thus stabilizing the blend's morphology. In general, the PA6/AES/EPDM-MA blend formulation (60/25/15%) showed potential for high-performance application, with prospects for the production of parts to supply the automotive and electronics industry market.

Las mezclas se prepararon en una extrusora de doble husillo co-rotacional y posteriormente se moldearon por inyección. Se evaluaron las propiedades de resistencia al impacto, resistencia a la tracción y morfología. Los resultados indicaron incrementos expresivos en la resistencia al impacto de las mezclas PA6/AES/EPDM-MA, en comparación con el PA6 puro. Sin embargo, el módulo elástico y la resistencia a la tracción sufrieron disminuciones, debido a la mayor flexibilidad de las mezclas desarrolladas. La mezcla PA6/AES compatible con un 15% de EPDM-MA se presentó como un material super tenaz y dúctil a temperatura ambiente. Las imágenes obtenidas por microscopía electrónica de barrido (SEM) indicaron que el aumento en el contenido de compatibilizador EPDM-MA favoreció la presencia de partículas más refinadas y bien adheridas en la matriz de PA6, estabilizando así la morfología de la mezcla. En general, la formulación de la mezcla PA6/AES/EPDM-MA (60/25/15%) mostró potencial para aplicaciones de alto rendimiento, con perspectivas de producción de piezas para abastecer el mercado de la industria automotriz y electrónica.Neste trabalho, a poliamida 6 (PA6) foi tenacificada com o terpolímero de acrilonitrila-EPDM-estireno (AES), utilizando o etileno-propileno-dieno enxertado com anidrido maleico (EPDM-MA), como agente compatibilizante. As blendas foram preparadas em uma extrusora de rosca dupla corrotacional e, posteriormente, moldadas por injeção. As propriedades de resistência ao impacto, resistência à tração e a morfologia foram avaliadas. Os resultados indicaram aumentos expressivos na resistência ao impacto das blendas PA6/AES/EPDM-MA, em comparação com a PA6 pura. Contudo, o módulo elástico e a resistência à tração sofreram decréscimos, devido ao aumento da flexibilidade das blendas desenvolvidas. A blenda PA6/AES compatibilizada com 15% de EPDM-MA apresentou-se como um material supertenaz e dúctil na temperatura ambiente. As imagens obtidas por microscopia eletrônica de varredura (MEV) indicaram que o acréscimo no teor do compatibilizante EPDM-MA favoreceu à presença de partículas mais refinadas e bem aderidas na matriz de PA6, estabilizando assim a morfologia da blenda. Em geral, a formulação da blenda PA6/AES/EPDM-MA (60/25/15%) apresentou potencial para aplicação de alto desempenho, com perspectivas para a produção de peças para suprir o mercado da indústria automobilista e da eletrônica.Research, Society and Development2021-08-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1879110.33448/rsd-v10i10.18791Research, Society and Development; Vol. 10 No. 10; e210101018791Research, Society and Development; Vol. 10 Núm. 10; e210101018791Research, Society and Development; v. 10 n. 10; e2101010187912525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/18791/16752Copyright (c) 2021 Pamela Thainara Vieira da Silva; Carlos Bruno Barreto Luna; Eduardo da Silva Barbosa Ferreira; Edson Antônio dos Santos Filho; Edcleide Maria Araújohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Pamela Thainara Vieira da Luna, Carlos Bruno Barreto Ferreira, Eduardo da Silva Barbosa Santos Filho, Edson Antônio dos Araújo, Edcleide Maria 2021-10-02T21:49:16Zoai:ojs.pkp.sfu.ca:article/18791Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:50.507915Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
