When the dispersed phase
is distributed as discrete domains in thermoplastic/elastomer blends, the particle size can be represented by a log-normal distribution .
Moreover, the addition of SEBS could make the dispersed phase
act as toughening particles of the blends, because of that SEBS was found to be compatible with PPO due to PS blocks.
Those results of sample (A) can be explained by the viscosity ratio of p= 0.13, the furthest from 1 of the tested blends (1 means that the viscosities of matrix and dispersed phase
In high viscosity ratio ([[eta]s.sub.d]/[[eta].sub.m]) blend systems, the low-viscosity matrix cannot efficiently transfer shear stresses to the high-viscosity dispersed phase
and acts as a lubricating phase around the dispersed phase
to reduce the break-up of droplets , Therefore, the dispersed phase
was dispersed with non-uniform domains in the continuous TPU phase.
The drop in tack is caused by a phase inversion, where the continuous phase is predominantly resin, and rubber is the dispersed phase
PA6/CNT nanocomposites from PA6/ CNT Nanocomposites section were incorporated as masterbatches into PP (PP/PA6-CNT: 80/20 wt/wt) as the dispersed phase
. The components were blended in the internal mixer at 240[degrees]C with a rotational speed of 50 rpm for 5 min.
The scientists found that by using release half-life (t50) as an indicator, a wide range of release rates, ranging from three minutes to 62 minutes, could be achieved, by simply adjusting the zein concentration in the dispersed phase
, and the continuous and dispersed phase

If the pH value becomes too low, the acidity difference between the material liquid phase and the dispersed phase
is too subtle and the migration effect will not be satisfying; If the pH of the material liquid becomes too high, it may cause the rare earth metal ion hydrolyse or form hydroxy complex, which affects the migration rate .
An increase in water (dispersed phase
) contents increased the number of droplets per volume of the emulsion resulting an increase in collision frequency and hence the stability was decreased (Fig.
Thus, values of the parameters increase uniformly with increase in the dispersed phase
concentration in emulsions.
In the present model, particle convective and radiative heat transfer coefficient consisted of the clusters and dispersed phase
so the above equation can be written as: h = fhwc + (1-f) hd + f (hwcr + (1-f) hdr (2)
