| 摘要 |
Organometallic polymers are made in liquid medium by contacting (A) bis-chelate ligands such as 1, 3, 5, 7-tetra (2-pyridylimino)-benzodipyrrole with (B) salts of divalent, hexacoordinate, transition metals such as nickel chloride. The organometallic polymers have high thermal stability and are suitable as colorants for organic materials including thermoplastic resins.
