Degradation Modeling of Biodegradable Medical polymer

The purpose of this article is to establish a mathematical model for the degradation process of biodegradable medical polymer materials. In order to making biodegradable polymer materials can be applied to the medical field successfully, an study about its degradation process is carried out. A sub-regional, sub-time degradation model is established according to the phenomenon that chemical reaction mechanism of surface and internal is not the same. The calculation is performed to solve the degradation model which we have established. In this article, we apply this model into the calculation of plate degradation. By the comparison of the calculation results, the experiment values and the calculated values of Pan´s model, a conclusion that this model is closer to experimental results compared with Pan´s model, and that this model is reasonable to experiment.
