Polymer degradation and stability中科院分区
WebPolymers degrade by several different mechanisms, depending on structure and exposure conditions. Degradation results from an irreversible change which leads eventually to failure. The most common types of degradation occur through chemical reactions, but there are a few important examples of degradation resulting only from physical changes.
