| 中文摘要: |
| 交联橡胶是一类典型的热固性高分子材料，一旦成型就难以重塑和再加工。大量废弃橡胶已经导致严重的“黑色污染”和资源浪费。升级回收利用和可持续发展是橡胶工业的重要需求。当前，除了回收利用现有的废弃硫化橡胶制品之外，从根源上解决橡胶材料绿色发展的关键在于开发可循环利用的新型交联橡胶。动态共价交联橡胶的发展为交联橡胶的高资源化回收利用提供了全新的机遇，但动态共价交联橡胶从概念走向实际应用仍面临诸多挑战。本文着眼于动态共价交联橡胶的连续再加工，总结了当前动态共价交联橡胶的发展现状以及所面临的困境，并对动态共价交联橡胶的发展提出了展望。 |

| Cross-linked rubber is a typical thermosetting polymer，which is difficult to be reshaped and reprocessed once molded.A large amount of waste rubber has caused serious “black pollution” and resource waste.As a result，upgrading recycling and sustainable development are important needs for the rubber industry.Currently，in addition to recycling existing waste vulcanized rubber products，the key to the green development of rubber materials from the root is to develop new type of recyclable cross-linked rubber.The development of cross-linked rubber by dynamic covalent bonds provides a unique opportunity for the high-value upcycling of the rubbers.However，the cross-linked rubber by dynamic covalent bonds still faces many challenges from the concept to real applications.In this contribution，the current development status and difficulties of cross-linked rubber by dynamic covalent bonds are summarized with focus on the continuous reprocessing technology，and the prospect for the development of cross-linked rubber by dynamic covalent bonds is put forward. |
