Polyvinyl resins, such as polyvinyl chloride (PVC), polyvinyl acetate, and polyvinyl alcohol (PVA), are produced by the polymerization of some sorts of vinyl monomers. Polyvinyl resins have been produced for various uses, and eventually become waste. We must take care of their incineration, especially PVC because of the evolution of harmful gases such as HCl and organic halogen compounds. In this measurement, we have examined the thermal decomposition of PVC and PVA by Thermo Mass Photo.
Thermo Mass Photo combines simultaneous thermal analysis with mass spectrometry. This technique is suitable for the qualitative analysis of evolved gases coincident with the STA signal.
In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
