| Abstract: | Block copolymers dissolved in selective solvent often self-assemble. We review the use of NMR to study this process and to characterize the aggregates formed. We stress the need to consider the polydispersity of the polymers and the fact that the increase in NMR relaxation rates observed upon aggregation can be assigned to contributions from the block copolymer micelle tumbling. |
