PREPARATION AND REACTIVITY OF METAL-CONTAINING MONOMERS .43. SYNTHESIS AND PROPERTIES OF COPOLYMERS OF STYRENE OR ACRYLONITRILE WITH TRIOSMIUM CARBONYL CLUSTER MONOMERS

The peculiarities of radical copolymerization of styrene or acrylonitr ile with triosmium carbonyl clusters whose ligand environments incorpo rate groups with multiple bonds capable of polymerization (4-vinylpyri dine, allylamine, acrylic acid) are described. Using IR and NMR spectr oscopy under the model conditions, it was shown that no side processes occur during the reaction of comonomers and azo-bis-isobutyronitrile, an initiator of radical polymerization. The cluster complex (the meta l core and its ligand environment) is retained during copolymerization . The molecular weight characteristics of the copolymers obtained were studied. The double bonds in the cluster monomers mostly retain the p roperties inherent in their organic analogs.
