Well-defined amphiphilic polymer conetworks with precisely controlled number and position of cross-links were prepared by copper-catalyzed azide-alkyne cycloaddition(CuAAC)using linear polystyrene(PS)and poly(ethylene glycol)(PEG)as the building *** this approach,linear polystyrene containing a specific number of bromo groups at a predetermined position of polymer chains was synthesized by multistep reversible addition-fragmentation chain transfer polymerization and chain extension using styrene and N-bromopropyl maleimide(PBMI)as the ***,the bromo groups were transformed into the azido moieties via nucleophilic *** well-defined linear multialkynyl PEG was prepared from PEG diglycidyl ether and propargylamine via epoxy-amine chain *** as-prepared PS-PEG amphiphilic polymer conetworks showed unique hydrophilic and hydrophobic phase separation with a variable swelling capacity and rheological behavior in both polar and nonpolar solvents and exhibited excellent mechanical properties with increased cross-linking density.
