Theory of viscoelastic behaviour of linear polymers in unimolecular approximation and its experimental verification
Summary The theory proposed in the present article determines the viscoelastic behaviour of concentrated polymer solutions and polymer melts with the aid of two parameters: the chain length between nodesg, or the numberu of nodes per macromolecule, and the monomeric friction coefficientζ0 which depe...

| 520 | |a Summary The theory proposed in the present article determines the viscoelastic behaviour of concentrated polymer solutions and polymer melts with the aid of two parameters: the chain length between nodesg, or the numberu of nodes per macromolecule, and the monomeric friction coefficientζ0 which depend, in a general case, on temperature, concentration, velocity gradients and the stresses applied. In this sense this theory, like the other theories of the viscoelastic behaviour of a macromolecular system proposed byMarvin andOser, Hayashi, Chompf, andDuiser is of a semi-phenomenological nature. The theory expounded above provides however a more consistent explanation of the viscoelastic behaviour of the polymeric systems under consideration in shear. The description of the most important specific features of the viscoelastic properties of polymeric systems under steady flow and oscillatory (cyclic) deformation is based on unified conceptions. The latter include the ratio of the first normal stress difference to the square of shear stresses; the variation of the viscoelastic functions and relaxation-time spectrum with increasing stresses or deformation amplitudes; the finalizing of the time-temperature superposition of the viscoelastic functions; the prediction of a loss of the fluidity of viscoelastic media with increase of shear stresses and rates, including the main features of this process. It should however be noted that this theory, as it follows from a detailed comparison with experiment, provides a qualitatively approximate description of the viscoelastic properties of monodisperse polymers. For example, the relaxation-time distribution in the region of transition from flow to the high-elasticity plateau appears to be somewhat different than that predicted by the theory. In distinction to what is predicted by the theory, a set of relaxation times in equivalent networks, corresponding to a decrease of molecular weight or to the application of stresses, is not equivalent. This and other shortcomings are an indication of the imperfection of the model which must be improved, probably by introducing intramolecular viscosity or hydrodynamic interaction. | ||

The description of the most important specific features of the viscoelastic properties of polymeric systems under steady flow and oscillatory (cyclic) deformation is based on unified conceptions. The latter include the ratio of the first normal stress difference to the square of shear stresses; the variation of the viscoelastic functions and relaxation-time spectrum with increasing stresses or deformation amplitudes; the finalizing of the time-temperature superposition of the viscoelastic functions; the prediction of a loss of the fluidity of viscoelastic media with increase of shear stresses and rates, including the main features of this process. It should however be noted that this theory, as it follows from a detailed comparison with experiment, provides a qualitatively approximate description of the viscoelastic properties of monodisperse polymers. For example, the relaxation-time distribution in the region of transition from flow to the high-elasticity plateau appears to be somewhat different than that predicted by the theory. In distinction to what is predicted by the theory, a set of relaxation times in equivalent networks, corresponding to a decrease of molecular weight or to the application of stresses, is not equivalent. This and other shortcomings are an indication of the imperfection of the model which must be improved, probably by introducing intramolecular viscosity or hydrodynamic interaction.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Viscoelastic Property</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Viscoelastic Behaviour</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hydrodynamic Interaction</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Normal Stress Difference</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Viscoelastic Medium</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pokrovsky, V.

| abstract |
Summary The theory proposed in the present article determines the viscoelastic behaviour of concentrated polymer solutions and polymer melts with the aid of two parameters: the chain length between nodesg, or the numberu of nodes per macromolecule, and the monomeric friction coefficientζ0 which depend, in a general case, on temperature, concentration, velocity gradients and the stresses applied. In this sense this theory, like the other theories of the viscoelastic behaviour of a macromolecular system proposed byMarvin andOser, Hayashi, Chompf, andDuiser is of a semi-phenomenological nature. The theory expounded above provides however a more consistent explanation of the viscoelastic behaviour of the polymeric systems under consideration in shear. The description of the most important specific features of the viscoelastic properties of polymeric systems under steady flow and oscillatory (cyclic) deformation is based on unified conceptions. The latter include the ratio of the first normal stress difference to the square of shear stresses; the variation of the viscoelastic functions and relaxation-time spectrum with increasing stresses or deformation amplitudes; the finalizing of the time-temperature superposition of the viscoelastic functions; the prediction of a loss of the fluidity of viscoelastic media with increase of shear stresses and rates, including the main features of this process. It should however be noted that this theory, as it follows from a detailed comparison with experiment, provides a qualitatively approximate description of the viscoelastic properties of monodisperse polymers. For example, the relaxation-time distribution in the region of transition from flow to the high-elasticity plateau appears to be somewhat different than that predicted by the theory. In distinction to what is predicted by the theory, a set of relaxation times in equivalent networks, corresponding to a decrease of molecular weight or to the application of stresses, is not equivalent. This and other shortcomings are an indication of the imperfection of the model which must be improved, probably by introducing intramolecular viscosity or hydrodynamic interaction. © Dr. Dietrich Steinkopff Verlag 1972 |
