Abstract
Vinyl acetate forms a complex with manganese tris(acetylacetonate). A scientific hypothesis, according to which the use of manganese tris(acetylacetonate) as an initiator would lead to the increase in the relative activity of vinyl acetate in copolymerization with more active monomers, is suggested. To verify the hypothesis experimentally, an integrated study of the kinetics of binary copolymerization of vinyl acetate with N-vinyl (N-vinylsuccinimide and N-vinyl-3(5)methylpyrazole) and acrylic (2-hydroxyethyl methacrylate) monomers in various media is carried out. It is demonstrated on the basis of an analysis of copolymerization constants of the monomers under study that the relative activities of monomers in fact become closer. This leads to a change of the microstructure of polymers and results in macrochains with improved alteration of monomer units.
