  • How does an efficient plasticizer interact with PVC?
  • An efficient plasticizer interacts with PVC and breaks the extended network of chain-to-chain dipole-induced dipole forces present originally in a polymer that is observed as an attenuation of a signal coming from the covalent bonds. The stronger the interactions, the more prominent the shift of particular peaks to the lower wavenumber .
  • How does plasticization affect spectral properties of PVC?
  • Plasticization of PVC results in a weakening of the intensity of both these bands . Moreover, the changes in spectral features of the plasticizer molecule can be followed to evaluate its interactions with PVC.
  • Does covalent bonding affect plasticization efficiency?
  • Covalent bonding of plasticizer molecules and PVC chains is an effective way to suppress the migration of a plasticizer from plastics. Although they not able to exhibit good plasticization efficiency, new internal plasticizers are still developed. There are several studies describing internal plasticizers and this issue is still being investigated.
  • Can Plasticizers improve the mechanical properties of poly (vinyl chloride)?
  • Multiple requests from the same IP address are counted as one view. This paper reviews the current trends in replacing commonly used plasticizers in poly (vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhancement in mechanical properties and better plasticizing efficiency.
  • Do plasticizers migrate from PVC to DOP?
  • As expected, the migration of plasticizers was equal to zero. Mechanical properties of the material with modified PVC were compared to a material plasticized by DOP. The commonly used plasticizer provided significantly lower tensile strength and higher elongation at break than the modified one.
  • Can bio-based plasticizers modify PVC?
  • In 2019, P. Jia et al. proposed a PVC modification using bio-based plasticizers based on cardanol, castor oil and ESBO. A graft modification of PVC was conducted with thiosalicylic acid. Although there was no plasticizer migration from the plastics, the mechanical properties were still poor in comparison to PVC/DEHP.
