Scaling of demixing curves and crossover from critical to tricritical behavior in polymer solutions

, 2002
In this paper we show that the virial expansion up to third order for the osmotic pressure of a dilute polymer solution, including first-order perturbative corrections to the virial coefficients, allows for a scaling description of phase-separation data ...
