Abstract This contribution reports on one-pot synthesis of crosslinked and branched copolymers via simple photoinduced free radical copolymerization strategy in the presence of methacrylated benzophenone, methyl methacrylate and N -methyldiethanolamine. Methacrylated benzophenone is used as a co-monomer and it is also responsible for the photoinitiation and coupling reactions simultaneously. Copolymerization experiments were carried out in several feed ratios of methacrylated benzophenone and the co-initiator upon ultraviolet irradiation. Polymerization results indicate that molecular weight values are directly depended on the concentrations of methacrylated benzophenone and co-initiator molecule. It is also observed that use of methacrylated benzophenone in mono-acrylate formulations may cause junction points in the copolymer structures.
