The length of a fully stretched chain is = for the Kuhn segment chain. [5] In the simplest treatment, such a chain follows the random walk model, where each step taken in a random direction is independent of the directions taken in the previous steps, forming a random coil .
In chain-growth polymerization the propagation step is the addition of a monomer to the growing chain. The word kinetic is added to chain length in order to distinguish the number of reaction steps in the kinetic chain from the number of monomers in the final macromolecule, a quantity named the degree of polymerization. In fact the kinetic ...
where each X i is the span of the corresponding Jordan chain, and k is the number of Jordan chains. One can also obtain a slightly different decomposition via the Jordan form. Given an eigenvalue λ i, the size of its largest corresponding Jordan block s i is called the index of λ i and denoted by v(λ i). (Therefore, the degree of the minimal ...
The persistence length equals the average projection of the end-to-end vector on the tangent to the chain contour at a chain end in the limit of infinite chain length. [4] The persistence length can be also expressed using the bending stiffness , the Young's modulus E and knowing the section of the polymer chain. [2] [5] [6] [7]
R is some length scale describing the chain conformation such as the radius of gyration or root-mean-square end-to-end distance of the chain. [2] Typically the pervaded volume is very large relative to the space actually occupied by the chain as most of the pervaded volume is usually filled with solvent or other chains. [1]

The number average molar mass is a way of determining the molecular mass of a polymer.Polymer molecules, even ones of the same type, come in different sizes (chain lengths, for linear polymers), so the average molecular mass will depend on the method of averaging.
