Zusammenfassung

Using rheometry and light scattering, we have studied the viscoelasticity of gels formed by the kinetically arrested phase separation in an emulsion-polymer mixture; to prevent the gels from collapsing under their own weight, we have used an isopycnic solvent. At constant osmotic pressure (set by the polymer concentration) and droplet volume fractions ø well above the gelation transition, we find the elastic modulus to increase roughly linearly with ø, indicating an entropic elasticity based on the cluster packing.
