Rheological properties related to the extrusion of polyolefins are shear viscosity, elongational slip velocity and their temperature- pressure-dependencies. These measured in rheology lab mainly via a parallel-plate rheometer capillary rheometer. Then appropriate rheological models have be used account for all these properties. Such either viscous (e.g., Cross model) or viscoelastic K-BKZ model...

The initial stages of spinodal decomposition were studied by subjecting a critical blend of model polyolefins to a pressure quench and monitoring the evolution by time-resolved small angle neutron scattering. Contrary to the predictions of the widely accepted Cahn-Hilliard-Cook theory, we demonstrate that coarsening of the phase-separated structure begins immediately after the quench and occurs...

The synergistic combination of sorbitol-based organogelators with polyolefins allows a fast and easy preparation porous support structures for immobilised phase change materials (PCM) in one step.

During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...
