What is Molecular Weight Types and Analysis about?
Molecular weight is defined as the sum of atomic weights of all atoms in a polymer molecule. Polymer molecules in a sample can have a range of molecular weights due to the statistical nature of polymerization. There are three types of average molecular weights - number average (Mn), weight average (Mw), and z-average (Mz). Mn is most influenced by lower molecular weight species while Mw is more influenced by higher molecular weight species. Polydispersity index (PDI), the ratio of Mw to Mn, is a measure of
