Rheological behavior for Polymer Melts and concentrated Solutions Part VII: A Quantitative Verification for the Molecular Theory of Non-linear Viscoelasticity with Entanglement Constraints in Polymer Melts

摘要

Based on the molecular theory of non - linear viscoelasticity with constrained entanglements in polymer melts, the materials functions in simple shear flow were formulated, the theoretical relations between η(γ), ψ_10 (γ) and shear rate (γ), and topologically constrained dimension number n' and a were derived.
