Poly(ethylene)-based blends with poly(acrylonitrile) copolymers by reactive blending for barrier applications

该项目应用反应性聚合物共混生产用于屏障应用的高附加值聚乙烯产品。这种方法在文献中得到了广泛的应用，但通常限于可以使用的聚合物类型。例如，将尼龙复合为细长结构，制成用于储气罐的聚乙烯，以防止聚乙烯膨胀。尼龙在聚（乙烯）基体内的这种形态是通过尼龙中固有的氨基和互补官能团（如马来酸酐）之间的反应性共混来稳定的，这些官能团可以很容易地接枝到聚（乙烯）上。在界面处原位形成的共聚物可防止在后续加工（如注塑或旋转成型）中分散相的聚结。然而，这种方法是有限的

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
