The group contribution mothod has been used to calculate the values of solubility parameter, intrinsic viscosity, Mark-Houwink parameters of ring-and linear shaped polystyrene according to cohesive energy, molar volume, molar attraction constant. All these calculating results were also experimentally demonstrated. Futhermore, the theoretical significance of the value of critical molecular weight used calculating the K_(θ,r) of ring-shaped polymer is detaily discussed.
