Thermoanalytical investigations for the recycling of PVC

Within a research project for the recycling of soft poly(vinylchloride) (PVC), analytical work has to be done. On the one hand, the raw material for the process needs to be checked for PVC content and for additional polymers and on the other hand, the recycled PVC needs to be characterized. In both cases, thermoanalytical methods especially coupled methods with gas analysis systems, can deliver suitable information for this characterization. The different investigations are presented, and evaluated regarding their informative capability.
