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.roneverhart.com/Mauri-Scenic-Men-s-Designer-Shoes-Gerbera-Red-Exotic-Ostrich-Loafers-3405-MA5118/
