However, the thermal stability of metallic coordination polymer hardly enhanced in comparison with the polymer never coordinated transitional metallic ions. The reason might be that the energy of coordinate bond formed between metallic ion and polymer was trival in comparison with that of covalent bond in polymer. It started with coordinate bond when the coordinate polymer decomposed under high temperature, so it engendered little for the thermal stability at high temperature.

而金属配聚物较未配位金属的配体高温热稳定性提高不大，可能是由于金属离子与配体之间形成配位键的键能与配位体内的共价键键能相比要小得多，当金属配聚物受热裂解时，首先从配位键开始，因此对高温热稳定性的影响甚微。
