Comparison of the Density and Solubility Parameter of Pure Plasticizers
The calculated solubility parameters for the pure plasticizers and PVC (previously listed in Table 3) are replotted in Figure 9 for easier comparison. Plasticizers all have much higher δ...
Solubility of Plasticizers, Polymers and Environmental Pollution
SOLUBILITY PARAMETERS AS A GUIDE FOR PLASTICIZER SELECTION. The compatibility of a plasticizer with a given polymer is very important. The maximum amount of plasticizer incorporated into a polymer at the processing temperature and retained by it without exudation during the storage, is commonly accepted as the practical limit of compatibility.
Determination of plasticizers efciency for nylon by
calculating cohesive energy density, solubility parameters, free volume and inter-action intensities of pristine nylon, and the nylon–plasticizer blends. It was found that the efciency of the plasticizers increases with the degree of interaction intensity between the plasticizer and polymer chains and that M4HB molecules
Solubility Parameter of PVC, DOP, and Rosin- Based Plasticizers
Plasticization is a major source of performance reduction in polymeric membranes, where uptake of specific vapour or liquid compounds affects either the space between macromolecular chains and thus...

- What are solubility parameter models?
- Solubility parameter models are widely used to select suitable solvents/nonsolvents for polymers in a variety of processing and engineering applications. In this study, we focus on two well-established models, namely, the Hildebrand and Hansen solubility parameter models.
- Why are plasticizers soluble in water?
- It arises from hydrophilic–hydrophobic properties of the molecules. Plasticizers, which are mainly the esters of relatively long alcohols, have a solubility in water of less than several milligrams per cubic decimetre (mg/dm 3) (see Table 3 ).
- Are plasticizers more soluble than PVC?
- The calculated solubility parameters for the pure plasticizers and PVC (previously listed in Table 3) are replotted in Figure 9 for easier comparison. Plasticizers all have much higher δ than PVC, and its value decreases monotonically with the alkyl side chain length. ...
- Why are plasticizers characterized by HSP?
- Many plasticizers have been characterized by HSP and their general behavior with regard to solubility and compatibility follows that of the solvents. Some differences are encountered due to generally higher molecular weights. This means lowered compatibility in boundary situations, and slower transport (diffusion) through polymer matrices.
- What are Hildebrand and Hansen solubility parameter models?
- In this study, we focus on two well-established models, namely, the Hildebrand and Hansen solubility parameter models. Both models are built on the basis of the notion of “like dissolves like” and identify a liquid as a good solvent for a polymer if the solubility parameters of the liquid and the polymer are close to each other.
- Does plasticizer molecular structure affect its performance?
- Effects of plasticizer molecular structure on its performance, as measured by performance metrics including its thermodynamic compatibility with PVC, effectiveness of reducing the material’s Young’s modulus, and migration rate in the PVC matrix, are evaluated in the framework of seven molecular design parameters.
