摘要：

A simple model for the calculation of configurational and rheological properties of finitely extensible polymers in flow is introduced. The finite extensibility of the chain is incorporated into the common Rouse model by varying the spring constant such that a constant contour length is maintained for every flow strength. For elongational flow, a comparison with Monte Carlo simulations of a bead-rod chain with 100 links yields qualitative agreement. For shear flow, this model predicts non-Newtonian flow behaviour.
