摘要

动态交联通用合成橡胶作为一种新兴的高性能材料，可以有效解决传统热固性橡胶优异力学性能、高稳定性与热塑性橡胶易加工、可回收难以兼顾的矛盾. 本综述系统梳理了动态共价网络(DCNs)的核心化学机理，对多种动态键进行了归纳，深入辨析了解离型与缔合型交换机制的本质区别、相互转化及其对材料宏观流变行为的影响. 随后，重点论述了对于不同化学结构通用合成橡胶针对性设计的动态交联策略与功能化实例. 最后，剖析了动态交联通用合成橡胶在工业化连续加工方面所面临的挑战与创新解决方案. 本综述旨在构建“化学机理—材料设计—加工应用”的完整闭环，为开发下一代高性能、多功能、可持续的合成橡胶提供依据与参考.

Abstract

Dynamically crosslinked synthetic rubber represents an emerging class of green

high-performance materials. These materials effectively resolve the trade-off between the superior properties of traditional thermosets and the facile processing and recyclability characteristic of thermoplastics. This review first systematically elucidates the core chemical mechanisms of dynamic covalent networks (DCNs) and categorizes the various dynamic bonds involved. A central focus is the in-depth analysis of the fundamental differences and interconversion between dissociative and associative exchange mechanisms. Subsequently

the discussion highlights tailored design strategies for dynamic crosslinking and their applications across synthetic rubbers with diverse chemical backbones. Finally

the challenges and prospective solutions for the continuous industrial processing of these materials are analyzed. Ultimately

this review seeks to establish a cohesive framework connecting fundamental chemistry with material design and processing applications. The goal is to provide a theoretical reference and valuable insights for developing the next generation of high-performance

multifunctional

and sustainable dynamic synthetic rubbers.
