Effect of Polydispersity on the Morphological Symmetry of Poly(methyl methacrylate)-block-polystyrene Copolymer Films

This study demonstrates that increasing the polydispersity of the poly(methyl methacrylate) block in PMMA-b-PS diblock copolymer films, synthesized via two-stage RAFT polymerization, induces a morphological transition from lamellar to cubic symmetry through an intermediate mixed phase.
