This project applies reactive polymer blending to produce value-added poly(ethylene) containing products for barrier applications. This approach has been widely applied in the literature but is generally limited to the types of polymers that can be used. For example, nylon is compounded as elongated structures into poly(ethylene) for gas tanks to prevent swelling of the poly(ethylene). Such morphologies of nylon within the poly(ethylene) matrix are stabilized by reactive blending between the amino groups inherent in the nylon and complementary functional groups like maleic anhydride that can be readily grafted onto poly(ethylene). The resulting copolymer formed in situ at the interface prevents coalescence of the dispersed phase during subsequent processing such as injection molding or rotational molding. However, such an approach is limited

该项目应用反应性聚合物共混生产用于阻隔应用的含增值聚乙烯产品。这种方法已广泛应用于文献中，但通常限于可以使用的聚合物类型。例如，将尼龙作为细长结构复合到用于气罐的聚（乙烯）中，以防止聚（乙烯）的溶胀。通过尼龙中固有的氨基和互补官能团如马来酸酐之间的反应性共混，可以稳定聚（乙烯）基质中尼龙的这种形态，所述互补官能团可以容易地接枝到聚（乙烯）上。在界面处原位形成的所得共聚物防止分散相在后续加工（例如注塑或旋转模塑）期间聚结。但是，这样的做法是有局限性的
