Schematic illustrates the two configurations considered to study the effect of differential oligomerization on condensate miscibility. The interfacial tension 12 in dimensionless units of / 2 , used as a measure of immiscibility, is consistently higher when the more homotypic IDR (more blocky charge patterning) in the pair is oligomerized. The represents the energy scale of interactions, while represents the size of a monomer bead. The bond ratio, defined as the ratio of unlike to like non-covalent bonds formed by the oligomerized IDR, is always lower for the system with the more homotypic IDR oligomerized.
