Molar Mass Determination
For polymeric materials, the molar mass or molecular size plays a critical role in determining the mechanical, bulk, and solution properties. These properties govern polymer processing, end-use performance, and stability. Therefore, determination of molar mass and molar mass distribution is of central interest in polymer analysis; see Chap. 1.
