In this equation, k is the number of monomers in the chain, [1] and 0<a<1 is an empirically determined constant related to the fraction of unreacted monomer remaining. [ 2 ] The form of this distribution implies is that shorter polymers are favored over longer ones — the chain length is geometrically distributed .
The main application of size-exclusion chromatography is the fractionation of proteins and other water-soluble polymers, while gel permeation chromatography is used to analyze the molecular weight distribution of organic-soluble polymers.
The mass average molar mass (often loosely termed weight average molar mass) is another way of describing the molar mass of a polymer. Some properties are dependent on molecular size, so a larger molecule will have a larger contribution than a smaller molecule.
The result is a much more broad molecular weight distribution, which leads to much larger dispersities. For a homogeneous CSTR, the dispersity is proportional to the square root of the Damköhler number , but for a heterogeneous CSTR, dispersity is proportional to the natural log of the Damköhler number .

The Schulz–Zimm distribution is a special case of the gamma distribution. It is widely used to model the polydispersity of polymers . In this context it has been introduced in 1939 by Günter Victor Schulz [ 1 ] and in 1948 by Bruno H. Zimm .
BuzzFeed collected McDonald's cups from different countries to see just how they compared -- and (un)surprisingly, cups in the USA were the biggest by far. In America, a small drink is 16 oz., a ...
