SYNTHESIS AND CHARACTERIZATION OF A COMB-LIKE POLYACETYLENE COPOLYMER

Graft copolymers were synthesized via lithiation of a polybutadiene backbone, transmetallation with titanium alkoxides and subsequent polymerization of acetylene. The products obtained were characterized by ultra-violet/visible spectroscopy, infra-red spectroscopy, wide-angle X-ray scattering and transmission electron microscopy. The 12 doped copolymers exhibit interesting electrical conductivity. The proposed percolation model accounts for the properties of these materials.
