We report the synthesis of quatrefoil-shaped star-cyclic polystyrene, star-cyclic PS, containing a polyhedral oligomeric silsesquioxane (POSS) core via the combination of atom transfer radical polymerization (ATRP) and click chemistry techniques. The obtained star-cyclic PS represents a new chain to...
