TG–MS analysis of nitrile butadiene rubber blends (NBR/PVC)

Pyrolysis of poly(vinyl chloride) and—electric arc furnacedust mixtures

“…The first region starts at around 230°C up to a temperature of 370°C, and is believed to be due to the decomposition (or de-hydrochlorination)by a free radical mechanism as reported in the literature [25]. Approximately 63% of the weight lossis related to the release of HCl, benzene and toluene [35]. …”

Insights into the use of zinc–mannitol alkoxide as a novel thermal stabilizer for rigid poly(vinyl chloride)

“…Figure shows the dynamic thermogravimetric curves of the PVC samples stabilized with different thermal stabilizers. According to Figure , there existed two distinct weight loss stages: the first stage was attributed to dehydrochlorination followed by the formation of conjugated polyene sequences, and the second one corresponded to the thermal cracking of carbonaceous conjugated polyene sequences to low‐molecular‐weight hydrocarbons and the generation of carbonaceous residues . Therefore, only the first stage was under discussion, and the temperature was in the range 25–375°C.…”

Analytical Methods

“…95 The volatile products were analyzed to investigate the interaction of the plastic blends during the thermal decomposition process. 96 The most remarkable change was the absence of HCl from decomposition products in the presence of the Mg(OH) 2 . 96 The most remarkable change was the absence of HCl from decomposition products in the presence of the Mg(OH) 2 .…”

“…95 TG-MS analysis of nitrile butadiene rubber blends with PVC was studied. 96 In summary, TGA is simple to use but it should be better avoided in PVC thermal degradation studies because many confusing findings are possible with this method. 96 In summary, TGA is simple to use but it should be better avoided in PVC thermal degradation studies because many confusing findings are possible with this method.…”
