During the flow of high molecular weight, narrow-, and broad-distribution polybutadienes and polyisoprenes rheo-optical measurements were conducted of extensional stresses acting along the flow axis in the preentrance and entrance regions of the duct and of their subsequent relaxation in the duct.

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
