6. Describe how the short range chemical structure of a polymer is related to its conformation in solution and derive an equation relating the mean square end-to-end distance of a random flight polymer to the number of formula units in a statistical segment. The radius of gyration for poly(styrene) in cyclohexane at 310 K was found to be 6.2 nm for a molecular weight of 50k. Given that the length of the formula unit is about 0.3 nm estimate the number of formula units in a statistical segment (the formula of styrene is C3H). No: of segments = 5.3
