Title
One-pot synthesis of water-soluble polymeric photoinitiator via thioxanthonation and sulfonation process
Abstract

One-pot synthesis of water-soluble side chain thioxanthone polystyrene (PSt-TX-WS) was achieved, and photoinduced polymerization of acrylamide (AAm) in water was performed with PSt-TX-WS in the presence of a tertiary amine. Since the amine is necessary for photopolymerization to occur, it is likely that PSt-TX-WS initiates polymerization of AAm according to the Norrish Type II reaction. The fluorescence quantum yield of PSt-TX-WS was found to be 0.021, and had a phosphorescence lifetime at 77 K of 95 ms.
