Solubility of Plasticizers, Polymers and Environmental
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.
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.
Interfacial effects of plasticizers on the properties
Solubility parameter method is widely applied to evaluate plasticizing effect. The following calculations were operated by referring to the A. Greco's method (Greco et al. 2010; Van Krevelen and Te Nijenhuis 2009a ). The solubility parameters of CDA and plasticizers can be achieved as following:
Selection of Solid-State Plasticizers as Processing Aids
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.
Effect of biodegradable plasticizers on thermal and
The calculated solubility parameters of PHBV and plasticizer are listed in Table 4. The solubility parameter ( δ ), and its polar and hydrogen bonding components ( δ p and δ h ) of DBP or TEC is closer to the corresponding values of PH BV than those of SO or ESO, whereas the dispersion component ( δ d ) of solubility parameter of SO and ESO
- 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.
- 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 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.
- 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?
- 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 ).
