vinyl--diketonate

Heterometal polymer complexes with -diketonate fragments have been obtained via styrene triple copolymerization with polyfunctional components of radical polymerization – vinyl--diketonates of 5-methyl-5-hexene-2,4-ditionates Mn(II) and Zn(II). The process was carried out in a block and dimethylformamide solution in the presence and absence of additional initiator – benzoyl peroxide. Varying the chelated metals concentration, the presence of solvent and additional initiator one may control the concentration and metal ratio in the macromolecule, as well as products molecular weight.

Bimetallic macroinitiators have been obtained via styrene triple copolymerization with cobalt(II) and manganese(II) vinyl--diketonates. The copolymerization kinetic parameters have been studied. Metal chelates were found to be as comonomers, initiators and inhibitors at the same time during copolymerization process. The macroinitiators synthesis optimal conditions have been examined. They may be used for the production of grafted polymers.
