Summary: A polymeric photoinitiator (PTXP) containing in‐chain thioxanthone (TX) and coinitiator amines was synthesized by step‐growth polymerization, as well as low‐molecular‐weight model compounds. Photopolymerizations of methyl methacrylate (MMA) initiated by these photoinitiator systems were studied. Compared with corresponding low‐molecular‐weight model compounds, PTXP has a similar UV‐vis spectrum with a red‐shifted maximum absorption, and weaker fluorescence emission, and can photoinitiate the polymerization of MMA more effectively.The structure of PTXP, the photoinitiator synthesized here.
