The objective of this article was preparation of curable silane‐grafted poly(ethylene‐1‐butene) nanocomposite. The poly(ethylene‐1‐butene) was a polyolefin elastomer with random high comonomer content. Two preparation methods were investigated. The method of preparing nanocomposites significantly affected the mechanical properties of the resulted nanocomposites. So that, with the same formulation and different preparation methods, silane grafting with the first was 94% (PVDS3), while with the second was 33% (PS3VD). It was shown that the tensile strength of the cured nanocomposite prepared with the method 1 (PVDS3) increased four times higher than the pure resin. The effects of different factors such as the amount of silane and also the amount of silicon carbide on the physical, mechanical, and thermal properties of the cured and uncured nanocomposites were investigated. The rate of curing was depended on the silicon carbide concentration and 5 phr (part per hundred resin), and nano‐SiC was a concentration where the tensile properties were optimum. Thermal stability and the impermeability of the cured samples improved in the presence of nano‐silicon carbide. J. VINYL ADDIT. TECHNOL., 26:244–252, 2020. © 2019 Society of Plastics Engineers

纳米SiC对硅烷接枝和聚烯烃弹性体固化的影响：混合顺序，物理和机械性能

本文的目的是制备可固化的硅烷接枝的聚（乙烯-1-丁烯）纳米复合材料。聚（乙烯-1-丁烯）是具有随机高共聚单体含量的聚烯烃弹性体。研究了两种制备方法。制备纳米复合材料的方法显着影响所得纳米复合材料的机械性能。因此，在相同的配方和不同的制备方法下，第一种硅烷的接枝率为94％（PVDS3），第二种硅烷的接枝率为33％（PS3VD）。结果表明，用方法1（PVDS3）制备的固化纳米复合材料的拉伸强度比纯树脂提高了四倍。不同因素（例如硅烷的量以及碳化硅的量）对物理，机械，并研究了固化和未固化的纳米复合材料的热性能。固化速率取决于碳化硅浓度和5 phr（每百种树脂的份数）以及纳米级SiC是拉伸性能最佳的浓度。纳米碳化硅的存在改善了固化样品的热稳定性和抗渗性。J.乙烯基添加物。TECHNOL。，26：244–252，2020.©2019塑料工程师协会
