Abstract

ABC triblock copolymers are known to exhibit wide variety of defferent types of morphologies compared with AB diblock copolymers. In the present study, a series of poly(styrene-block-isoprene-block -(methyl methacrylate)) and poly(styrene-block-(ethylene-co-propylene)-block-(methyl methacrylate)) triblock copolymers were synthesized and their morphologies were extensively studied by transmission electronmicrotomography (TEMT). In one of the triblock copolymers, a very complicated three-dimensional (3D) structure, called "ladder pattern" was found.
