交联高性能聚合物具有许多工业应用，但难以回收或返工。成功制备了一类新型的可循环交联Cu（II）-金属-超分子配位聚合物，具有优异的热稳定性和力学性能。更重要的是，Cu 2+配位相互作用可以通过外部焦磷酸盐进一步去除以回收线性聚合物，这赋予交联聚合物可回收性。
Crosslinked high‐performance polymers have many industrial applications, but are difficult to recycle or rework. A novel class of recyclable crosslinking Cu(II)‐metallo‐supramolecular coordination polymers are successfully prepared, which possess outstanding thermal stability and mechanical property. More importantly, the Cu2+coordination interactions can be further removed via external pyrophosphate to recover the linear polymers, which endow the crosslinking polymers with recyclability.
