PREPARATION AND REACTIVITY OF METAL-CONTAINING MONOMERS .38. THERMODESTRUCTION OF POLYSTYRENE AND POLYACRYLONITRILE MODIFIED WITH TRIOSMIUMCARBONYL CLUSTER MONOMERS

Modified polystyrene and polyacrylonitrile possessing cluster fragment s in polymer chains have been obtained by radical copolymerization of styrene or acrylonitrile with triosmium carbonyl cluster complexes hav ing double bonds capable of polymerization in their ligand surrounding s. The thermal stability of the copolymers produced has been studied b y DTG analysis. The temperature increase characteristic of both polyme r and cluster pyrolysis has been observed for clusters containing poly styrene. The cluster complexes have been also shown to influence to a great extent the destruction of polyacrylonitrile, thus preventing the formation of stable fused structures in polymer chains.
