Abstract / Description of output

We examine the demixing transition in star-polymer-colloid mixtures for star arm numbers f = 2,6,16,32 and different star-polymer-colloid size ratios 0.18 less than or equal toq less than or equal to0.50. Theoretically, we solve the thermodynamically self-consistent Rogers-Young integral equations for binary mixtures using three effective pair potentials obtained from direct molecular computer simulations. The numerical results show a spinodal instability. The demixing binodals are approximately calculated and found to be consistent with experimental observations.
