Abstract

Phenylethynyl-terminated imide (PETI) oligomers are highly valued for their diverse applications in films, moldings, adhesives, and composite material matrices. PETIs can be synthesized at varying molecular weights, enabling the fine-tuning of their properties to meet specific application requirements. Upon thermal curing, these oligomers form super-rigid network structures that enhance solvent resistance, increase glass-transition temperatures, and improve elastic moduli. Their low molecular weights and melt viscosities further facilitate processing, making them particularly suitable for composites and adhesive bonding. This review examines recent advancements in developing ultra-high-temperature PETIs, focusing on their structure-processing-properties relationships. It begins with an overview of the historical background and key physicochemical characteristics of PETIs, followed by a detailed discussion of PETIs synthesized from monomers featuring noncoplanar configurations (including kink and cardo structures), fluorinated groups, flexible linkages, and liquid crystalline mesogenic structures. The review concludes by addressing current challenges in this research field and exploring potential future directions.

苯乙炔基酰胺低聚物热固性树脂。

苯乙炔基端亚胺（PETI）低聚物因其在薄膜、模塑、粘合剂和复合材料基材中的多种应用而备受推崇。PETI 可以以不同的分子量合成，因此可以对其特性进行微调，以满足特定的应用要求。热固化后，这些低聚物会形成超刚性网络结构，从而增强耐溶剂性、提高玻璃转化温度并改善弹性模量。它们的低分子量和熔体粘度进一步促进了加工，使其特别适用于复合材料和粘合剂粘接。本综述探讨了开发超高温 PETI 的最新进展，重点关注其结构、加工和性能之间的关系。综述首先概述了 PETI 的历史背景和关键理化特性，然后详细讨论了由具有非共面构型（包括扭结和 Cardo 结构）、氟化基团、柔性连接和液晶中原结构的单体合成的 PETI。综述最后讨论了这一研究领域当前面临的挑战，并探讨了未来可能的发展方向。

期刊介绍： Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
