Radius of gyration of stiff chain molecules as a function of the chain length and the interactions with the solvent
Abstract
The radius of gyration and the second osmotic virial coefficient of a model chain molecule is calculated numerically with a Monte Carlo procedure. The model is intended to resemble cellulose trinitrate (CTN). The expansion coefficients of stiff chain molecules such as CTN or DNA are near unity at high molecular weights and in good solvents.
