摘要：

Dynamics of thin layers of entangled polymers is considered theoretically using a generalization of the reptation model. It is shown that monomer-monomer excluded volume interactions suppress long-range motion of polymer chains, giving rise to an exponential increase of the longest relaxation time and the viscosity eta as the layer thickness is decreased. Explicit dependencies of In a on concentration, molecular weight, and thickness are obtained.
