The effect of polymolecularity on the radius of gyration of stiff polymer chains

The z‐average of the unperturbed mean‐square radius of gyration, 〈S2〉o,z, is calculated for polymolecular Kratky‐Porod worm‐like chains, commonly used to represent stiff polymer chains. Polymolecularity correction factors for the Schulz‐Zimm and logarithmic normal distribution functions are tabulate...

Description
Summary:The z‐average of the unperturbed mean‐square radius of gyration, 〈S2〉o,z, is calculated for polymolecular Kratky‐Porod worm‐like chains, commonly used to represent stiff polymer chains. Polymolecularity correction factors for the Schulz‐Zimm and logarithmic normal distribution functions are tabulated. By contrast with those for unperturbed random coils, they depend significantly on the chain length.
