Based on Shull’s theory, the system of A/B diblock copolymer present at immisciblehomopolymer interface was studied. We obtained the relationship between the interfacialtension and the excess amount of copolymer at interface as a function of various degree ofpolymerization of the copolymer. The copolymer having a lower degree of polymerization ismore efficient than that having a higher molecular weight since the number of chains islarger for a shorter chain for a given amount of coplymer at interface. When the number ofcoplymer at interface is fixed to be same, the longer copolymer is somewhat more efficientthan the shorter one.
