ABC triblock copolymers are known to exhibit wide variety of different 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-alt-propylene)-block-(methyl methacrylate)) triblock copolymers were synthesized and their morphologies were extensively studied. In one of the triblock copolymers, a very complicated three-dimensional (3D) structure that looked like "knitting pattern" was observed (see Fig. 2 above). The 3D structures will be examined by transmission electron microtomography (TEMT) at the conference time.
