Abstraet-An appraisal of the rheological model proposed in Part I is presented. The experimental data on six fluids (four polymer solutions. one soap solution and one polymer melt) are used to test the model in various flow situations: steady simple shearing; oscillatory, small-amplitude simple shea
## Abstract Constitutive equations are derived for the timeβdependent behavior of semicrystalline polymers at isothermal loading with small strains. A semicrystalline polymer at temperatures above the glassβtransition point for its amorphous phase is thought of as a network of macromolecules bridge
