Abstract: The interfacial tension of coacervates, the liquidlike phase composed of oppositely charged polymers that coexists at equilibrium with a supernatant, forms the basis for multiple technologies. Here we present a comprehensive set of experiments and molecular dynamics simulations to probe the effect of molecular mass on interfacial tension $\ensuremath{\gamma}$, far from the critical point, and derive $\ensuremath{\gamma}={\ensuremath{\gamma}}_{\ensuremath{\infty}}(1\ensuremath{-}h/N)$, where $N$ is the degree of polymerization, ${\ensuremath{\gamma}}_{\ensuremath{\infty}}$ is the infinite molecular mass limit, and $h$ is a constant that physically corresponds to the number of monomers of one chain within the coacervate correlation volume.
