Aldrich Polymer Products Applicaton & Reference Information
Solubility parameter values are based on heats of vaporization. The values obtained with this method give estimates of solu-tion behavior. It is recommended that the reader consult the reference given below2 or other references for a more detailed explanation of δ values. Table II: Solubility Parameters for Plasticizers and Solvents
Structure Design, Performance Simulation and Plasticizing
Solubility parameters and solubility parameter of different plasticizers listed in Table 4 are obtained from formula 5 and 6 . High plasticizing efficiency of plasticizer for PVC is attributed to plasticizer’s good compatibility with PVC and its high diffusion in PVC, which result from the interaction between plasticizer and PVC molecules.
Solubility of Plasticizers, Polymers and Environmental Pollution
It means that the difference between solubility parameters of compatible polymer and plasticizer should be less than approximately 4 MPa 0.5. For example, PVC having a δ value of 21.4 MPa 0.5 is compatible with DBP, DEHP and ditridecyl phthalate over the whole range of concentration.

- 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.
- 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 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 ).
- 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.
- Is plasticizer compatible with a polymer?
- 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.
- 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.
