WebIn terms of Flory’s characteristic ratio, the mean square distance is given by R 2 = C n n l 2. The Flory characteristic ratio, C n, increases with the increase in the number of monomers. For n ≫ 1, it saturates to a finite value C ∞, yielding R 2 ≈ C ∞ n l 2. Webangles occur and mathematical developments lead to introduce a characteristic ratio C ...
