Application Notes: Polymers

In addition to the weight-average molar mass and the polydispersity, the DAWN can also determine the shape of the polymer by measuring the rms radius directly at each elution volume. It is well-known that butadiene forms highly branched polymers and that styrene forms linear polymers-and this is revealed by the DAWN.

Synthetic elastomers have replaced natural rubber to an astonishing degree, and account for more than 70% of the rubber used today.
