Abstract

Polyethylene (PE) and polypropylene (PP) are among the most widely produced macromolecular alkanes; however, there is an urgent need to introduce diverse functional groups into these materials to meet the demands of modern technologies. The incorporation of oxime functionality has garnered significant attention; however, the direct postfunctionalization to access such materials remains a considerable challenge. In this work, we report a mild iron-catalyzed method for the C–H imidoylation of polyethylene and polypropylene. This approach enables the efficient installation of oxime functionality into diverse commodities and postconsumer polyolefin plastics. New properties not found in virgin PP, such as enhanced hydrophilicity, improved compatibility in mixed plastic blends, and increased adhesion to aluminum and steel plates, are exhibited in these functionalized materials. These enhanced characteristics highlight great potential for further applications. Additionally, the successful use of real-world plastics offers a sustainable strategy to broaden the utilization of plastic waste.

通过铁催化的C-H酰基化将肟官能团引入聚烯烃

聚乙烯（PE）和聚丙烯（PP）是生产最广泛的大分子烷烃；然而，迫切需要在这些材料中引入多样化的官能团，以满足现代技术的要求。肟功能的结合引起了极大的关注；然而，直接后功能化访问这些材料仍然是一个相当大的挑战。在这项工作中，我们报告了一种温和的铁催化聚乙烯和聚丙烯的C-H酰化方法。这种方法能够有效地将肟功能安装到各种商品和消费后聚烯烃塑料中。在这些功能化材料中表现出了未在原始PP中发现的新性能，例如增强的亲水性，改善的混合塑料混合物的相容性，以及增加的与铝和钢板的附着力。这些增强的特性突出了进一步应用的巨大潜力。此外，现实世界塑料的成功使用为扩大塑料废物的利用提供了可持续的战略。

期刊介绍： Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
