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
(3) χ = (δ p δ pl) 2 V r (R T) 1 where V r is an average volume of plasticizer molecule and polymer repeated units and δ p and δ pl are solubility parameters for polymer and plasticizer. Therefore, one of the most common approaches is to use the δ values of both components for the initial estimation of compatibility.
Interfacial effects of plasticizers on the properties
Solubility parameter method. 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:

Comparison of the Density and Solubility Parameter of Pure
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...
- What are the solubility parameters for solvents and plasticizers?
- Solubility parameters for solvents and plasticizers are provided in Table II and Table III in alpha-betical order and in order of increasing δ value, respectively. The same is provided for homopolymers in Table IV. As a guide, the solubility parameter difference, (δpolymer - δsolvent), must be small for good miscibility.
- 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. ...
- What is a good plasticizer concentration?
- In practical formulations the plasticizer concentration usually varied from 5 to 40 wt%. Plasticizers play also an important role as processing aids. They act as lubricants, reduce adhesion to metal surface, lower processing temperature, reduce melt viscosity, improve ductility and lower film forming temperature in dispersions.
- 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.
- 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.
- Can plasticizer improve the plasticity of polyvinyl chloride (PVC)?
- Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved.
