The preparation of coordination polymer (CP) alloys is demonstrated by the use of two meltable, one-dimensional crystal structures via melt-kneading. The polymer structures of the alloys are studied by synchrotron X-ray absorption and scattering, solid-state NMR spectroscopy, DSC, and viscoelastic measurements. Crystalline and amorphous domains and thermal properties (melting and glass transition) in the alloys depend on the ratio of the two constituent CPs. The glassy alloy composed of an equivalent amount of two CPs shows high plastic deformation properties, and the fracture point reaches 128% without a filler or compatibilizing agent, hence behaving as ductile materials.
通过熔融共混使用两种可熔融的一维晶体结构证明了配位聚合物（CP）合金的制备。通过同步加速器X射线吸收和散射、固态核磁共振光谱、差示扫描量热法和粘弹性测量研究了合金的聚合物结构。合金中的结晶和非晶域以及热性能（熔点和玻璃化转变）取决于两种组成CP的比例。由等量的两种CP组成的玻璃态合金表现出高塑性变形性能，在没有填料或增容剂的情况下断裂点达到128%，因此表现为韧性材料。
