A new silsequioxane based macro-initiator with eight initiating sites was prepared from a selective hydrosylation of T8 silsequioxane, and used to synthesize water soluble star polyacrylamide containing inorganic-core through atom transfer radical polymerization (ATRP). The generated polymers exhibit good solubility in water, controlled molecular weights and narrow polydispersity.

Key words: star polymer, polyacrylamide, atom transfer radical polymerization (ATRP), siloxane based six-faced structure
