The coordinative-radical polymerization of new monomers in the presence of azoizobutyronitrile (AIBN) as an initiator, in different solvents at 80 degrees C has been. studied. The photoinitiated polymerization of several metal-containing monomers is described,. Six metal chelates were investigated as monomeric units: copper (11), nickel (II), cobalt (II) complexes with 5-methyl-5-hexen-2,4-dione, 7-octen-2,4-dione and 3-allylpentan-2,4-dione in the photo polymerization processes which have been studied by the dilatometry. Synthesized complexes (in very small quantities 1-5%) were copolymerized with styrene. The beta-diketonates of Ni, Co, Cu can be used as new class of intrachain, UV-absorbers.
