Abstract

The mechanism of the formation of soluble and network polymers during the process of anionic polymerization of oligoesteracrylates (OEA) was investigated. It was shown that the network polymer was built from charged branching macromolecules. The anionic polimerization of OEA establishes the equilibrium in the process of electron distribution between functional groups of OEA and equilibrium between soluble and network polymers and residual OEA. Both types of equilibria are determined by the temperature and the ratio of concentration of OEA and catalyst. The equilibrium in the system of network and soluble polymers and residual OEA is established both by the interaction of catalyst with OEA and with “dead” network polymer which may be “vitalized” in this way.
