Kinetics of the photosensitized polymerization of oligocarbonate methacrylate

Layer-by-layer photosensitized polymerization of oligocarbonate methacrylate was studied in presence of donor-acceptor initiating systems differing by the chemical nature and size of the oligoester block in oligomeric tertiary amines (proton donors). The results of kinetic investigations showed that tertiary amines, including oligomeric ones, play the most important role in the photosensitized polymerization of oligocarbonate methacrylate. This process is proposed to proceed through the formation of donor-acceptor complex with the participation of methacrylic chain fragments and tertiary amino groups.
