通过使用多次挤出，特别考虑到加工前材料干燥的影响，从瓶子中回收PET。水解断链和热机械降解导致PET的性能显著下降。然而，值得注意的是，在三次挤出后，性能的下降速率下降;在进一步的再循环步骤中，没有观察到性能的显著变化。
Recycling of PET from bottles has been carried out by using multiple extrusions, considering in particular, the effect of drying of the material before processing. Hydrolytic chain scission and thermomechanical degradation induce a remarkable reduction of the properties of PET. It is worth noting, however, that the rate of decrease of the properties drops after three extrusions; with further recycling steps no remarkable changes of the properties are observed.
