title = "Universality of block copolymer melts",
abstract = "Simulations of five different coarse-grained models of symmetric diblock copolymers are compared to demonstrate a universal (i.e., model-independent) dependence of the free energy and order-disorder transition (ODT) on the invariant degree of polymerization {\=N}. The actual values of χN at the ODT approach predictions of the Fredrickson-Helfand (FH) theory for {\=N}104 but significantly exceed FH predictions at lower values characteristic of most experiments. The FH theory fails for modest {\=N} because the competing phases become strongly segregated near the ODT, violating an underlying assumption of weak segregation.",
