Zusammenfassung:The ability of copper(II) complexes with 4-phenylthiosemicarbazide and amino acid anions to act as initiators of polymerization of methyl methacrylate and styrene is shown. It was found that the activation energies of polymerization and initiation in the presence of copper(II) complexes are significantly reduced in comparison with the process of thermal initiation. It is established that polymerization of methyl methacrylate initiated by the studied complexes resulted in the formation of syndiotactic polymer.
