Rheology and Other Instrumental Techniques

Instrumental methods are among the most powerful techniques for polymer analysis. Because of their simplicity, sensitivity, versatility, and speed, their applications in polymer analysis are growing at a rapid pace. Polymer testing has come a long way from the determination of molecular weight with respect to molecular properties used for in-situ monitoring of rheological behavior.

Rheological testing is often necessary to assess processing characteristics. Rheology is widely used to provide information about the molecular structure and composition of polymeric systems [1]. Characteristics of interest include molecular weight, molecular-weight distribution, level and type of long-chain branching, ...
