Composition and chemical heterogeneity

Nevertheless, the utility of SEC in copolymer analysis is not impaired, if one applies SEC keeping the limitations described above in mind. The rapidity, simplicity, and capability of obtaining much data on copolymers by SEC overcome those drawbacks. In this chapter, the methods of determining molecular mass averages and MMD, as well as composition and chemical heterogeneity, are described. Other separation modes of HPLC used with the size-exclusion mode, such as the adsorption mode, are also explained.
