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.
