Branching Analysis of PMMA

Branching PMMA

The degree of branching and its distribution in a polymer affects its physical and chemical properties. Characterization with a DAWN® or miniDAWN® coupled to a chromatograph provides the only direct method of determining the branching ratio, gM, and, from a knowledge of the branching functionality, the branching frequency as a function of molecular weight. Other techniques are indirect at best, and are based on numerous assumptions.
