The Tg of the neat PVC is 84°C, meanwhile, the Tg of the PVC-PDMS, PVC-TBC1, PVC-Oleic, and PVC-TBC2 were decreased to 62.6, 53.0, 42.8, and 41.0°C, resp. By

Two natural plasticizers derived from cardanol (CD), cardanol acetate (CA) and epoxidized cardanol acetate (ECA), were synthesized and characterized by 1H NMR and 13C NMR. The plasticizing effects of the obtained plasticizers on semi-rigid polyvinylchloride (PVC) formulations were also investigated. Two commercial phthalate ester plasticizers, dioctyl

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 .
Does plasticizer concentration affect TG?
We find the average Tg determined from fast dynamics decreases substantially with increasing plasticizer concentration, consistent with volumetric Tg obtained from the temperature dependence of density.
How does internal plasticization affect the movement of PVC chains?
Internal plasticization extends the distance between PVC chains and weakens the interaction between main chains by grafting long flexible chains. This process effectively prevents the migration of the plasticizer, makes PVC flexible, and promotes the movement of PVC chains.
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.
Are secondary plasticizers a synergistic effect?
A separate chapter has been dedicated to the description of a synergistic effect of a mixture of two plasticizers, primary and secondary, that benefits in migration suppression when secondary plasticizer is added to PVC blend.
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.
