| Abstract: | PET and photovoltaic backsheet based on the PET were treated by those ageing methods, such as hygrothermal ageing and thermal oxidation ageing and so on. Then elongation at break of PET and backsheet after ageing were tested. Afterwards, the changes of functional groups, crystallinity, molecular weight and elongation at break in the process of ageing were analyzed by means of FT-IR, DSC, viscosity and mechaical property tesing. And then the relationship between these property changes and the mechanism of material microstructure changes was investigated. |

| Keywords: | photovohaic backsheet PET crystallinity elongation at break |
