Abstract

Polyolefins are the largest-scale synthetic plastics and play a key role in modern society. Their production consumes huge amounts of fossil-derived monomer feedstocks, which unfortunately became discarded wastes after use with a very low recycling ratio, causing severe environmental pollution and huge consumption of non-renewable resources. This lack of sustainability could in principle be solved by reusing the waste polyolefins repeatedly as virgin materials or recovering olefin monomers for re-entering the polyolefin cycle. However, it is challenging due to their chemical inertness (C-H and C-C bonds) and lack of degradation sites along the polyolefin chains. Therefore, to make polyolefins more sustainable, degrading or modifying the waste polyolefins on large scales could facilitate their reuse as virgin polyolefins or recovery to polymerizable feedstocks, rethinking the design and synthesis from monomer feedstocks could afford inherently recyclable and thus more sustainable polyolefin or polyolefin-like materials. Given the above, this review will introduce recent progress in the rapidly advancing field: 1) Recycling and upcycling to fuels and other small molecule products, olefin monomer, telechelic products, reprocessable and functional polyolefin materials; 2) Increasing sustainability by the de novo design and synthesis of new degradable and reprocessable polyolefin and polyolefin-like polymers.

聚烯烃化学的可持续发展:进展、挑战与展望
聚烯烃是规模最大的合成塑料,在现代社会中发挥着关键作用。它们的生产消耗了大量来源于化石的单体原料,这些原料在使用后不幸成为废弃废物,回收率很低,造成了严重的环境污染和不可再生资源的巨大消耗。这种缺乏可持续性的问题原则上可以通过重复利用废弃聚烯烃作为原始材料或回收烯烃单体重新进入聚烯烃循环来解决。然而,由于它们的化学惰性(C-H和C-C键)和缺乏沿聚烯烃链的降解位点,这是具有挑战性的。因此,为了使聚烯烃更具可持续性,大规模降解或改性废弃聚烯烃可以促进其作为原始聚烯烃的再利用或可聚合原料的回收,重新考虑单体原料的设计和合成可以提供固有的可回收性,因此更具可持续性的聚烯烃或类聚烯烃材料。鉴于此,本文将介绍这一快速发展的领域的最新进展:1)回收和升级为燃料和其他小分子产品、烯烃单体、远旋产物、可再加工和功能聚烯烃材料;2)通过重新设计和合成新的可降解和可再加工的聚烯烃和聚烯烃类聚合物来提高可持续性。

期刊介绍: Progress in Polymer Science is a journal that publishes state-of-the-art overview articles in the field of polymer science and engineering. These articles are written by internationally recognized authorities in the discipline, making it a valuable resource for staying up-to-date with the latest developments in this rapidly growing field. The journal serves as a link between original articles, innovations published in patents, and the most current knowledge of technology. It covers a wide range of topics within the traditional fields of polymer science, including chemistry, physics, and engineering involving polymers. Additionally, it explores interdisciplinary developing fields such as functional and specialty polymers, biomaterials, polymers in drug delivery, polymers in electronic applications, composites, conducting polymers, liquid crystalline materials, and the interphases between polymers and ceramics. The journal also highlights new fabrication techniques that are making significant contributions to the field. The subject areas covered by Progress in Polymer Science include biomaterials, materials chemistry, organic chemistry, polymers and plastics, surfaces, coatings and films, and nanotechnology. The journal is indexed and abstracted in various databases, including Materials Science Citation Index, Chemical Abstracts, Engineering Index, Current Contents, FIZ Karlsruhe, Scopus, and INSPEC.
