    Notes: Experimentally determined viscosities, first and second normal stress differences, and compliances for concentrated solutions of linear and four-arm star-branched polystyrenes and polybutadienes depend on the shear rate and the molecular weight, in agreement with theory and previously reported experimental results. The ratios of the second to first normal stress difference are -0.29 and -0.214 for the linear and branched polymers, respectively, independent of molecular weight, molecular weight distribution, concentration, and shear rate.
