Polymer Crystallization Researches under Shear Flow and Deformation

Abstract

In this study, we evaluated the effect of molecular weight on the formation of a shish–kebab morphology on a wide spatial scale. Here we examined blended polyethylene with 97 wt% deuterated polyethylene and 3 wt% protonated polyethylene comprising molecules with a range of molecular weights. Measurements were conducted with various X-ray and neutron scattering techniques. The nanometer-scale analysis revealed that the crystal lattice is also independent of the molecular weight. Moreover, small-angle X-ray and neutron scattering measurements did not reveal any influence of molecular weight.
