### Abstract

We used a self-consistent mean field theory to determine the adsorption behavior of AC and BC comb copolymers at the interface between two immiscible homopolymers, A and B. The backbones of the AC combs are composed of A monomers, and the side chains (teeth) are formed from C units. In a similar manner, the BC combs have a B backbone and C teeth. The C segments are themselves immiscible with both the A and B homopolymers. Taking into account the effect of micelle formation, we calculate the reduction in interfacial tension caused by the adsorption of these combs at the A/B interface. At the interface, the combs form a 'bilayer': the C teeth associate across the A/B boundary and the backbones remain localized in the respective homopolymers. Our results show that for an optimal choice of comb architecture, the interfacial tension can be reduced to zero. Consequently, these combs constitute effective compatibilizers and emulsifying agents.
