Abstract:

Polyolefin elastomer (POE) is a high-end polyolefin material that is copolymerized from ethylene and α-olefin. It has excellent properties such as chemical stability, weather resistance and electrical insulation, and is widely used in various fields such as photovoltaic, automobile and cable. Dynamic-chemical cross-linking (DCC) can further improve its mechanical properties and thermal stability, and expand its application range while ensuring its processability. This paper reviews the preparation methods of DCC POEs, including one-step direct cross-linking and multistep cross-linking after functionalization. The functionalization methods, such as post-functionalization and copolymerization of ethylene and functional monomer, are elaborated. The characterization methods of DCC POEs and the relationship between their chain structure, aggregation structure and properties are discussed. The future prospects of DCC POEs are also presented. This paper aims to provide theoretical guidance and technical support for the controlled synthesis, structure-activity relationship study and high value application of DCC POEs, and to promote the innovation and development of high-end polyolefin materials.

Key words: polymer reaction engineering, high-end polyolefin, polyolefin elastomer, dynamic-chemical cross-linking, functionalization, structure-activity relationship

摘要:

聚烯烃类弹性体是由乙烯与丙烯或其他高碳α-烯烃共聚而成的高端聚烯烃材料,具有出色的化学稳定性、耐候性和电绝缘性,广泛应用于光伏、汽车、电缆等领域。通过动态化学交联可在保证其加工性的前提下,进一步提高其力学性能与热稳定性,拓展应用范围。综述了动态化学交联聚烯烃弹性体的制备工艺,包括一步法直接交联和功能化后再交联(多步法)。详细介绍了后功能化、乙烯与功能化单体共聚等功能化方法。讨论了动态化学交联聚烯烃类弹性体的表征手段及其链结构、聚集态结构和性能之间的关系。展望了动态交联聚烯烃类弹性体的未来发展。为动态化学交联聚烯烃类弹性体的可控制备、构效关系研究以及高值应用提供理论指导与技术支持,推动高端聚烯烃材料的创新和发展。
