Berbat T. Vinyl-beta-diketonates of transition metals as inhibitors and initiators in the radical polymerization.

Vinyl-beta-diketonates of transition metals as initiators, co-monomers and inhibitors in the radical polymerization have been explored. The use of vinyl-beta-diketonates as initiators of radical polymerization allows to obtain polymers with the grafted structure. The influence of both the ligand structure and metal nature in the vinyl-beta-diketonates has been studied. The effective low temperature initiating system of APD (Со) – PB for conducting of MMA radical polymerization has been offered, considerably excelling on efficiency of PB. Independently on metal and ligand nature vinyl-beta-diketonates show both initiating and inhibiting actions. The range of PMMA samples has been explored on the stability to thermooxidating destruction. The polymers obtained by vinyl-beta-diketonates initiation possess greater stability in comparison with the polymers produced by using of peroxide initiator.
