Dimensions Of Rings And Chains In DUute Solution By Small Angle Neutron Scattering. Theoretical predictions of the z-average mean-square radii of gyration (z,c=o) for flexible linear and cyclic polymers with the same number of skeletal bonds in dilute solution at the 6-point, which are unperturbed by excluded volume effects, predict a ratio of 2,c=o / = 2.0 [42] [43] [44] (where 1 refers to...
