摘要: A bead and spring model is considered for the Brownian dynamics simulation of behavior cyclic polymer chains (rings) in a dilute solution under shear or elongational flow. Finite extensibility, excluded volume, hydrodynamic interaction are taken into account to make as realistic possible. In flow, deformation chain rate viscosity dependence (the flow curve), studied characterized. coil-stretch phenomenon described relationship between critical molecular weight given. The qualitative obtained ring polymers analogous that linear polymers.
