KINETICS OF THE PHOTOSENSITIZED POLYMERIZ ATION OF OLIGOCARBONATE METHACRYLATE

Layer-by-layer photosensitized polymerization of oligocarbonate methac rylate was studied using donor-acceptor systems differing by the chemi cal nature and size of oligoester block in oligomeric tertiary amines (proton donors). The results of kinetic investigations showed that ter tiary 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 a donor-a cceptor complex with the participation of methacrylic chain fragments and tertiary amino groups.
