英文摘要	The Monte Carlo method was used to investigate the effect of graft length and architecture on the efficiency of compatibilization in A/B/graft copolymer ternary blends. In this study, homopolymer B is always dispersed phase. When the graft length of the copolymer is relatively short, A(20)B(n) copolymers (A block is the backbone, and B block is the graft) tend to form micelles in the matrix phase, whereas the B(20)A(n) (B block is the backbone, and A block is the graft) copolymers tend to form micelles in the dispersed phase. We also find that the micelles in the dispersed phase (formed by B(20)A(n) copolymers) can effectively suppress the coalescence of the dispersed phases, whereas the micelles in matrix phase (formed by A(20)B(n) copolymers) have no effect on suppressing the coalescence. As a result, when the graft length is relatively short, B(20)A(n) copolymers can lead to smaller dispersed phases than A(20)B(n) copolymers. Moreover, when the graft is relatively long, A(20)B(n) copolymers were found to connect the dispersed phases and form netlike structure, whereas B(20)A(n) copolymers were found to locate at the phase interface and anchor the dispersed phase and matrix phase. Furthermore, both A(20)B(n) and B(20)A(n) copolymers with relatively long graft lengths can well reduce the size of the dispersed phase.
