| Abstract: | Simultaneous formation and polymerization of polyphenylacetylene (PPA) films by Nd(AA)3-Fe(AA)3-Al(i-Bu)3 or Nd(BA)3-Fe(BA)3-Al(i-Bu)3 mixed, coordination catalysts was carried out in the toluene/hexane solvents at room temperature. The features and kinetic behaviour of polymerization, and properties of PPA films have been investigated. It is pointed out that neodymium-ferrum mixed catalysts show combined catalytic effects. |
