molekulatömegátlagok
Molekulatömegátlagok, commonly referred to as molecular weight averages, are important parameters used to describe the size distribution of polymers. Polymers are long chains made up of repeating smaller units called monomers. In a real sample of a polymer, the chains are not all the same length. This variation in chain length leads to a distribution of molecular weights. Molecular weight averages provide a single numerical value that represents the typical molecular weight of the polymer chains in a sample.
Several types of molecular weight averages exist, each emphasizing different aspects of the distribution. The number-average
The ratio of Mw to Mn, known as the polydispersity index (PDI), is a measure of the
