Squalane and polymer surface density profiles obtained by CGMD at 450 K for systems with differing unlike interaction parameter k_ij, ranging from attractive (k_ij = −0.1) to repulsive (k_ij = +0.005). The partial density of oligomers is shown by bold lines, and the partial density of polymers is shown by dashed lines. Surface enrichment varies from a small concentration increase at the surface to a pure squalane surface layer. An initial constant global squalane concentration of 40% (w/w) was used for each simulation. Results for higher values of k_ij are shown in the Supporting Information.
