The (Gell-Mann-Low type) renormalization group theory is applied to frictional properties of dilute polymer solutions for the first time. The universal ratios such as Flory's intrinsic viscosity constant, the Flory-Scheraga-Mandelkern parameter, etc., are estimated from the first order ε-expansion theory (ε=4-d, d being the spatial dimensionality). The results are in satisfactory agreement with experimental results in both the nondraining Gaussian and nondraining self-avoiding limits. Preaveraging the Oseen tensor makes the value of the intrinsic viscosity about 10% larger according to the first order ε-expansion calculation.
