## Abstract A modification of a viscometer originally proposed by Zimm and Crothers in 1962 is presented, which may be used to measure ultra low shear viscosity for highly dilute polymer solutions. This may provide useful information on polymer coil dimensions and relaxation time. Use of the low sh
A systematic framework introduced recently to obtain parameter-free predictions of material properties of dilute polymer solutions in extensional ows is reviewed. The essential constraint of ensuring that the model polymer molecule has a ΓΏnite length is met by using a bead-spring chain model with ΓΏn
