According to the experiment results of degradation in field, degradation mechanism of the biodegradable mulch film can include four stages: the first, the material surface appeared deficiency while the surface area and interstice increased of material in the action of natural environment and microorganism; the second, along with the surface area and interstice of material increased and the gap strengthened, the chemical chain of the high polymer's principal chain broke as a result of the hydrolysis or the enzymatic effect in the action of hydration, causing the molecular weight and mechanics function descended; the third, the molecular of high polymer split the low polymer after its physical mechanical function descended, the material decomposed the fragments, the mass defect intensified; the fourth, the low polymer of fragments form in the natural environment, the microorganism, the biological enzyme became the smaller fragments, thus absorbed by the phagocytes, or further turn into CO2 and H2O due to hydrolysis.

根据田间降解试验结果推测，生物全降解地膜的降解机理可能包括四个阶段：第一，在自然环境、微生物作用下，材料表面出现缺陷，同时表面积增大、空隙增多；第二，随着材料表面积的增大、空隙的增多，吸水性增强，在自水合作用下，高聚物主链由于水解或酶解而使化学链断裂，导致分子量和力学性能下降；第三，在其物理机械性能下降后，高聚物分子链断裂为低聚物分子，材料裂解为碎片状，质量损失加剧；第四，碎片状低聚物在自然环境、微生物、生物酶作用下进一步水解变成尺寸更小的碎片，从而被吞噬细胞吸收，或进一步水解，生成CO2和H2O。

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。
