The dependence of shear and elongational viscosity on the molecular weight of poly(vinylidene fluoride) has been studied using a capillary rheometer. The elongational viscosity was evaluated based on Cogswell's method with two types of capillaries: capillary length (L)/capillary diameter (D) Ο 10 mm
An ultra-high molecular weight polyethylene (UHMW-PE) fiber was prepared by gel spinning using general kerosene as the solvent and gasoline as the extraction solvent. The process of the phase separation of gel as-spun, spun under various spinning conditions, was investigated. Its extracting and dryi
## Abstract The anomaly of shear thickening at high shear rates can be observed under certain conditions for high molecular weight polymers dissolved in lowβviscosity Newtonian solvents despite the fact that shearβthinning behavior is considered the norm for these fluids. The nature of the shearβth
