摘要：
This paper reports experimental evidence of non universal behavior of the reduced viscosity versus the reduced concentration C/C* in semi-dilute good solvent solutions of linear polymers. Results manifest two semi-dilute regimes: non-entangled and entangled, and outline the role of the number N(e) of blobs between entanglements. This number is a constant which depends on the polymer species and causes the universality failure.
