Summary The vortices in laminar flow of high molecular weight polyethylene oxide melt under shear were studied using small angle light scattering technique and applying the statistical and model aproaches. It was found that vortices are aggregates of large number of molecules with the core of fluctuating density and molecular orientation of surroundings due to this rotation. Perpendicular dimensions of the more dense core is 4.3 μm and for oriented surroundings 7,5 μm. Longitudinal dimensions are 8 μm and 20–35 (depending on shear rate) for the dense and oriented parts, respectively.
