Synthesis of tadpole-shaped PUSS-containing hybrid polymers via click chemistry

Copper-catalyzed alkyne-azide click chemistry is applied in the preparation of tadpole-shaped (monochelic) POSS-end functional hybrid polymers by combining with ATRP and RAFT polymerization. Alkyne-functionalized ATRP initiator and RAFT agent were respectively synthesized and applied in the preparation of alkyne-terminal poly(methyl methacrylate) and polystyrene. The tadpole-shaped POSS-containing hybrid polymers are easily obtained by the click reaction with an azido-functional POSS molecule. This presents a novel and effective method to prepare POSS-containing hybrid polymers. (C) 2010 Elsevier Ltd. All rights reserved.
