We perform computer simulations of mechanically linked (poly[2]catenanes, PC) and chemically bonded (bonded rings, BR) pairs of self-avoiding ring polymers in steady shear. We find that BR's develop a novel motif, termed gradient tumbling, rotating around the gradient axis. For the PC's the rings are stretched and display another new pattern, termed slip-tumbling. The dynamics of BR's is continuous and oscillatory, whereas that of PC's is intermittent between slip-tumbling attempts. Our findings demonstrate the interplay between topology and hydrodynamics in dilute solutions of connected polymers.
