| Abstract: | Bisphenol a polycarbonate (PC) is one of the most widely used engineering thermoplastic owing to excellent physical and chemical properties.When bisphenol a polycarbonate is used in outdoor applications, it starts to show losses in mechanical properties due to sunlight, humidity and oxygen. To increase its lifetime, this undesirable degradation process needs to be overcome. Therefore, it is necessary to know what chemical degradation reactions occur and how these processes are initiated. This review briefly... |
