A model of polymer chains as compressible elastic spheres in flow is presented. The spherical polymer blobs are assumed to compress in simple Couette flow in accord with recent rheo-optic measurements on semi-dilute solutions. The experimentally determined decrease in radius with increasing shear rate is predicted by the model. https://www.nacrack.com/mega-pick-Legacy-Kelly-Green-Spear-Cool-Fit-Adjustable-Visor-White-quick-deal/
