Block copolymers are of great current interest, as routes to self-assembled nanostructures in solution and in bulk. Advances in controlled synthetic methodologies have greatly expanded access to such materials, yet routine characterization techniques are in some aspects inadequate. Block copolymers present particular challenges for characterization by size-exclusion chromatography (SEC), which will be identified and discussed. This webinar will review how adding detection by multi-angle light scattering (SEC-MALS) can solve some of these issues as well as the remaining difficulties.
