Role of plasticizer in thermal-oxidative breakdown of polyvinylchloride in the presence of metal chlorides

Investigation into the Decomposition Pathways of an Acetal-Based Plasticizer

“…Although hydrolysis appears to be the major decomposition pathway of BDNPA/F, there are several other significant decomposition products discovered via the F-ratio analysis. The weakest bond in BDNPA/F has been calculated to be the C−N bond, with an activation energy of 42 kcal mol −1 , using the B3LYP/6-31G(d,p) level of theory, so we hypothesized that C− N bond homolysis, forming the carbon-based radical (11) and NO 2…”

“…Plastics are found in a variety of applications in modern society, including packaging, household appliances, and electronics, due to their unique physical, mechanical, and electrical properties. − However, there are often unwanted attributes of plastics such as high rigidity that make post synthetic processing of the plastic difficult. To tune the physical properties of a polymer, a plasticizer is often added to improve the rheology of the resulting plastic composite. − However, plasticizers have issues of their own, such as their loss due to evaporation, migration, and/or chemical decomposition, resulting in the degradation of the polymer composite. − It is also possible that plasticizer decomposition products may react with the polymer, causing its chemical decomposition, further degrading the plastic composite. , …”
