Density function analysis of single polymer chain

We study the conformational properties of single polymer chain both with and without electric charge. We propose a new method by considering the conformational properties of single polymer chain. In stead of traditional approaches, we introduce the density function of polymer segments. And we calculate the physical quantities from this new approach. For the most simple and the most important case, we confirm that Flory's exponents ν reproduce 3/5, which is completely same as the Flory's. We discuss the problems related to the improvement of this new concept that will be useful in future studies.
