Chain-end modification of low molar mass polybutadienes allowed the formation of thermoreversible networks based on the Diels–Alder chemistry. Furan telechelic polybutadienes with various chain length were first synthesized. Addition of a bis-maleimide (BM) compound to the liquid polymer led to the formation of elastomeric networks. Properties of this material were highly affected by the chain length of the polymer precursor and the cross-linking density, monitored by changing the quantity of the BM compound. Finally, the capacity of recycling of the rubber was shown by remolding the used material over five cycles without mechanical properties loss.

基于可逆Diels-Alder化学的可回收远螯交联聚丁二烯
低摩尔质量的聚丁二烯的链端修饰使基于Diels–Alder化学的热可逆网络得以形成。首先合成了具有不同链长的呋喃远螯聚丁二烯。向液体聚合物中添加双马来酰亚胺（BM）化合物导致形成弹性体网络。这种材料的性能受到聚合物前体的链长和交联密度的高度影响，通过改变BM化合物的量来监测。最后，通过在五个周期内重塑使用过的材料而无机械性能损失，显示了橡胶的回收能力。
