摘要：

The variation of morphology of triblock copolymers of the ABC type, poly(isoprene-b-styrene-b-2-vinylpyridine), with composition was studied by transmission electron microscopy. Four types of morphology were observed for the microphase-separated structures of the samples whose volume fractions of the middle-block polymer, polystyrene, range from 0.3 to 0.8, while keeping the volume fractions of the end-block polymers, i.e., polyisoprene and poly(2-vinylpyridine), equal. They are a three-phase four-layer lamellar structure, an ordered tricontinuous double-diamond structure, a cylindrical structure composed of two kinds of cylindrical domains formed by two end-block polymers in a polystyrene matrix, and a spherical structure composed of two kinds of spherical domains formed by two end-block polymers in a polystyrene matrix. The variation of morphology with composition is discussed in comparison with that of diblock copolymers.
