Results showed that PEG/pHPMAlac/HAMA hydrogels were characterized by hydrophilic, HAMA-richer internal domains dispersed in a more hydrophobic continuous phase, composed of PEG/pHPMAlac, and that the volume fraction of the dispersed phase increased by increasing HAMA concentration.
This trend toward smaller void sizes suggests an increase in emulsion stability with higher PFPA incorporation, which is likely the result of the higher organic content helping to form wider and more robust continuous phase films around the internal phase droplets.
As expected, for the same polystyrene grade at a concentration in the blend below 20wtt%, a polypropylene matrix having a higher viscosity enables the formation of a more co-continuous phase morphology than a less viscous one, as quantified by solvent extraction.
When carrageenan was present, the aroma compounds were found to be more concentrated in the continuous phase than in the dispersed phase.
In the compatibilized PA6/ PP/PP MA)/(PS/SMA) blends, PA6 phase was no more continuous but gets finely dispersed in the PS continuous phase.
In all cases, the continuous phase was more viscous and wetted the bounding walls.
It was found that the PA6 was more likely to form the continuous phase, and a complete co-continuous composition range did not exist.
In rugby union, the action is far more continuous, with play often going many phases and spreading across the length and width of the field.
This surfactant should exhibit relatively fast adsorption dynamics, which is more critical when the surfactant in the continuous phase has slower dynamics.
