Correlation of Polymer Performance and Hansen Solubility Parameters
… of this research was to investigate formulation parameters and how they affect grout performance. It was learned that particle size and oil absorption (OA) value are important filler properties that affect performance as much as adequate packing density and optimal pigment volume concentration …

Application of Hansen Solubility Parameters and Thermomechanical Techniques to the Prediction of Miscibility of Amorphous Solid Dispersion. Investigating the role of cohesive energy and free volume to predict phase separation kinetics in hot-melt extruded amorphous solid dispersion using dynamic mechanical analyser, shear rheometer and solubility parameters data
… is increasingly employed to improve the solubility of poorly water-soluble drugs. The technique relies on the enhanced solubility of the amorphous form of the drug compared to its crystalline counterpart. These systems however are thermodynamically unstable. This means that the drug …

Using Covalent and Non-Covalent Chemistry to Control Properties of Single -Walled Carbon Nanotubes
… with sodium cholate surfactant. Solution-phase solubility without surfactants can be achieved using high levels of covalent functionalization with aryl hydroxyl or aryl carboxylic acid moieties. Polymer theory based models for the Hildebrand and Hansen solubility parameters confirm the effect of …

The effect of hydrocarbon exposure and temperature on the behaviour of elastomeric seals
… aromatic rings) as well as increasing all Hansen solubility parameters increased swelling. Of the Hansen solubility parameters, the greatest correlation was found with the hydrogen-bonding (electron exchange) parameter. Nonetheless the dispersion parameter which is strongly affected by the …

Simultaneous Degradation of Toxic and Volatile Substrates by Two Phase Partitioning Bioreactor Systems: Performance Characterization and Rational Polymer Selection
… using three different methods, Hildebrand solubility parameters, Hansen Solubility Parameters (HSP) and activity coefficients at infinite dilution. It was found that the HSP method gave the best trends and its predictions had better agreement with the experimental results. Consequent …

Understanding Functional Silica Additives for HDPE Composite Materials
… The solvent identification was based on the Hansen solubility parameters and the findings correlate with the solubility predictions. The incorporation of all types of pyrogenic silica were seen to facilitate solvent ingress into HDPE at low and high loading levels. The findings in this work …

The Use of Solubility Parameters to Select Membrane Materials for Pervaporation of Organic Mixtures
… temperatures. The paint processing industry uses Hansen solubility parameters (HSP) to indicate polymer solubility. The potential of this method to predict solvent-polymer affinity was investigated for screening potential membrane materials for the pervaporation of a model solution containing …

Rational Design of Poly(phenylene sulfide) Aerogels Through Precision Processing
… through the manipulation of various processing parameters, such as polymer concentration, post-process annealing conditions, mode of manufacturing (casting versus additive manufacturing), dissolution temperature, and drying method. The ultimate goal was to elucidate key …
