Synthesis and morphological study of flexible/semi-rigid diblock copolymers, 1996:leaf 18 (Since block copolymers are polymer molecules consisting of chemically dissimilar, terminally connected segments, their sequential arrangement can vary from A-B (diblock) structures, just having two segments only, to A-B-A triblock copolymers with three segments, to multiblock or star-block (A-B) systems having many segments)
