Selection of Solid-State Plasticizers as Processing Aids for Hot-Melt
Similarly, plasticizers with solubility parameter in the range of 13-27 MPa are likely to show complete or partial miscibility with EPO. 41 In addition, solubility parameter determination should be supplemented with other complementary testing such as calorimetric and viscosity measurements to judiciously select solid-state plasticizer for melt extrusion process. 42

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
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.
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...
Selection of Solid-State Plasticizers as Processing Aids for Hot-Melt
Solubility parameters, thermal analysis, and rheological evaluation were used as assessment tools. Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers.
- Which solid-state plasticizers are used in a chemistry study?
- Solubility parameters, thermal analysis, and rheological evaluation were used as assessment tools. Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers.
- What is a solid state plasticizer?
- Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers. Binary and ternary physical mixtures were evaluated as a function of plasticizer concentration for thermal and rheological behavior.
- Are plasticizers miscible with API and polymer?
- Based on the solubility parameter, plasticizers such as SA, GB, and PEG showed Δδ (API) and Δδ (polymer) < 7 MPa ½, and they are likely to be miscible with the API and polymer. These plasticizers are expected to form a one-phase system with the INM-EPO mixture.
- 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. ...
- Are plasticizers miscible?
- Greenhalgh et al. 40 have demonstrated that components with solubility differences of less than 7 MPa ½ are likely to be miscible. Thus, plasticizers with solubility parameters in range of 17-31 MPa ½ are likely to show complete or partial miscibility with INM.
- 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 ).
