We reported a novel method of producing the cross-linked polybutadiene elastomer which could be thermally recycled like the plastic materials without the sacrifice of functional utility. The commercial polybutadiene was first attached with furan via thiol–ene reaction, and the cross-linked network was then built via Diels–Alder click reaction between the bismaleimide and attached furan groups from polybutadiene. The obtained polymer had good solvent resistance from ambient temperature to 100 °C. The mechanical properties of modified polybutadiene could be tailored by the amount of attached furan and the ratio of furan to bismaleimide. Furthermore, the dynamic cross-linked polybutadiene had good thermally remolded and self-healing behaviors. By this method, the dynamic cross-linked polybutadiene could be recycled to use in a sustainable way. Concerning all the raw materials were available in large quantities without tedious and multistep synthetic routes, this work demonstrated the high performance recycling solution to the commercial cross-linked polybutadiene, which might be applied in industry in relatively short time.

通过硫醇-烯和狄尔斯-阿尔德点击化学的交联聚丁二烯弹性体的生态友好方案

我们报道了一种新的生产交联聚丁二烯弹性体的方法，该方法可以像塑料材料一样进行热循环，而不会牺牲功能性。商业化的聚丁二烯首先通过硫醇-烯反应与呋喃连接，然后通过双马来酰亚胺与聚丁二烯连接的呋喃基团之间的Diels-Alder点击反应建立交联网络。所获得的聚合物在环境温度至100℃下具有良好的耐溶剂性。改性聚丁二烯的机械性能可以通过连接的呋喃的量和呋喃与双马来酰亚胺的比例来调整。此外，动态交联的聚丁二烯具有良好的热重塑和自修复性能。通过这种方法，可以动态回收动态交联的聚丁二烯，以可持续的方式使用。
