Non-Linear Rheological Properties and Neutron Scattering Investigation on Dilute Ring-Linear Blends
Abstract
Linear and non-linear Rheology on dilute blends of polystyrene ring polymers in linear matrix is combined with <br/>Small Angle Neutron Scattering (SANS) investigations. In this way 2 different entanglement interactions become <br/>clear. After stretching the samples to different hencky strains up to 2 in a filament stretching rheometer, followed <br/>by quenching, strong anisotropic scattering patterns were obtained which were described by affinely deformed <br/>rings which function as giant, polymeric chemical crosslinks or sliplinks and more or less isotropic topological <br/>contributions from the entangling with interpenetrating linear chains. At the same time the non-linear rheological <br/>and mechanical data fit to a non-affine slip-tube model as for moderately crosslinked networks and to interchain <br/>pressure models or a modified non-linear Doi-Edwards description for the observed strain hardening during the <br/>extensional rheology. The entangled situation is thought to be responsible for the different terminal behaviour <br/>observed in ring polymers with traces of linear impurities. A comparison with a dilute blend of a linear chain of the <br/>same size as the ring polymer in the longer matrix is made.
