  • Which Green plasticizers are used for internal plasticization of PVC?
  • In this study, the tributhyl citrate (TBC), propargyl ether tributhyl citrate (PrTBC), oleic acid and poly (dimethylsiloxane) diglycidyl ether terminated (PDMS, Mn ≃ 800) have been used as four different green plasticizers to internal plasticization of PVC.
  • Is green plasticization useful for plasticization of PVC with higher Termal stability?
  • The results showed that this green approach is not only useful for plasticization of the PVC with higher termal stability, but also for inhibition of the migration of the plasticizer molecules.
  • Does PVC oleic have a higher thermal stability than neat PVC?
  • The modified PVCs, especially PVC-oleic and PVC-PDMS, have higher thermal stability than to neat PVC. Tensile strength decreased from 41.35 MPa down to 25.01 MPa by substitution of chlorine atom with plasticizer agents, and the elongation at break increased from 40.80% up to 90.27%, demonstrating the PVC was plasticized efficiently.
  • Can covalent plasticization of PVC reduce human health risks?
  • Hence, the results showed that plasticization of the PVC was successfully performed by these covalent plasticization without any migration. These strategies are expected to be scalable, and provide a viable alternative to the use of phthalates, thus decrease the human health threat and environmental risks. 1. Introduction
  • Which thermograms indicate lower Tg for modified PVC compared to unmodified PVC?
  • The DSC thermograms indicate lower Tg for modified PVC compared to unmodified PVC. The Tg from 84 °C in PVC was decreased to 62.6, 53.0, 42.8, and 41.0 °C in PVC-PDMS, PVC-TBC 1, PVC-Oleic, and PVC-TBC 2, respectively. Therefore, they can be used at semi-rigid to semi-flexible materials.
  • How is propargyl ether tributyl citrate (prtbc) synthesized?
  • Synthesis of propargyl ether tributyl citrate (PrTBC) Propargyl ether tributyl citrate was synthesized by dissolving of 8.0 ml (~23 mmol) of TBC, 2.8 ml (~25 mmol) of propargyl bromide solution, and 3.18 g (~23 mmol) of potassium carbonate in 30 ml of acetone.
