Effect of acetylated citrate plasticizer on mechanical
The total mass loss was 83.73% at 800 °C. Compared with pure PVC, the thermal stability of TBC/PVC was poor, and the mass loss was 78.71% in the temperature range of 200 °C–400 °C. The total mass loss of TBC/PVC was as high as 93.87% due to thermal decomposition of TBC.
Internally plasticized PVC by four different green
The TGA thermograms indicate the M-PVC materials, especially PVC-PDMS and PVC-Oleic, have higher thermal stability than PVC. The internally plasticized PVCs show the lower Tg compared to PVC. The Tg of the neat PVC is 84 °C, meanwhile, the Tg of the PVC-PDMS, PVC-TBC, PVC-Oleic, and PVC-TBC Graphical abstract Download full-size image Keywords
Synergistic Effect of Two Plasticizers on Thermal Stability
At the same time, the plasticizer is another important processing additive for PVC. It enters between the molecular chains of PVC, and weakens the intermolecular force, resulting in the improvement of the thermal stability of PVC and the flexibility of PVC products.
Research progress of novel bio-based plasticizers and their
Abstract Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing. Owing to the negative impact of petroleum-based plasticizers on human health

- 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.
- How are internal plasticized PVCs prepared?
- In this study, the internally plasticized PVCs were prepared by four different green plasticizing agents. Self-plasticization of PVCs were performed by covalently bonding of TBC, PrTBC, oleic acid and PDMS (Mn ≃ 800) as internal plasticizers to PVC matrix.
- What are phthalate-free internal plasticized polyvinyl chloride (PVC) materials?
- In this work, the phthalate-free internally plasticized polyvinyl chloride (PVC) materials were developed by covalent attachment of tributyl citrate (TBC), propargyl ether tributyl citrate (PrTBC), oleic acid, and poly (dimethylsiloxane) diglycidyl ether terminated (PDMS, Mn ≃ 800) to the PVC matrix.
- Why are PVC oleic and PVC-TBC 2 prepared materials more flexible?
- The prepared materials from PVC-HDI precursor (PVC-oleic and PVC-TBC 2) have a lower Tg compared to others. This can be related to the presence of the HDI at them, which caused the higher free volume at them and result in more flexibility. These materials due to their diverse Tg amounts can be employed in semi-rigid to flexible applications.
- 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.
- How to self-plasticize PVC?
- Self-plasticization of PVCs were performed by covalently bonding of TBC, PrTBC, oleic acid and PDMS (Mn ≃ 800) as internal plasticizers to PVC matrix. The prepared M-PVCs through different synthesis routes abbreviated with PVC-TBC 1, PVC-TBC 2, PVC-Oleic, and PVC-PDMS, respectively.
