Abstract
In this paper a model theory of concentration effects for polydispersed polymers was presented. It is based these facts and assumptions that the total concentration effects are considered as the summation of the individual concentration effect, that each effects have also been explained as the consequence of both the reduction of hydrodynamic volumes and the viscosity phenomena of each species, and the entanglements between the macromolecules are negligeable. The relationships between the concentration of injected solutions with the hydrodynamic volumes, the elution volumes and the polydispersed index of hydrodynamic volumes were derived from this model theory. It can predict quantitatively the effects of concentration on the shift of peak elution volumes, the axial spreading and the skewing effects for polydispersed polymers.Keywords
