摘要：

The Brownian dynamics technique was used to simulate the kinetics of neutral and charged polymer chains in elongational flow. A macromolecule is represented by a dumbbell with conformation-dependent parameters. The simulation results were compared with predictions of the Peterline-de Gennes kinetic equation. It was shown that the theory works quite well beyond the limits of 'coil-stretched chain' transition region.
