Characterizing the Average Composition and Molar Mass Distributions of a Copolymer by SEC–MALS–dRI–UV

The chemical composition of a copolymer material has a substantial impact on its properties and performance. Defining a composition profile is therefore an essential aspect of product development for these materials. The copolymer’s composition often varies considerably with molecular weight (MW), and in the R&D process, therefore, it requires a detailed analysis which maps out composition across the entire MW distribution.
