| Abstract: | We describe adsorption of neutral flexible polymer chains onto small colloids that can be covered by one chain. We discuss the structure of star-shaped complexes and their abundance in dilute solution. In semi-dilute solution similar complexes form crosslinks between chains and cause gelation. |
