WP2304: Analysis of polymers in organic solvents by FFF-MALS

In this article, FFF-MALS and its applications in characterization of technical polymers are reviewed. Several examples, relevant to the most important application areas, are demonstrated via measurements performed in the author´s laboratory. The results acquired by FFF-MALS are contrasted with those produced by size-exclusion chromatography with light scattering (SEC-MALS) which, despite being markedly better known and more widely utilized, often fails to describe the true molecular structure of many technically important polymers such as elastomers, acrylic emulsion copolymers, branched polymers or macromolecular materials containing nanogels or nanoparticles.
