Abstract: Two kinds of noncyclic polyether Schiff bases condensed from salicylic aldehyde and diethylene or tetraethylene glycol diamine have been obtained. Four complexes of these Schiff bases with Co(Ⅱ) or Ni(Ⅱ) nitrates have been synthesized and characterized by IR,UV,1 NMR respectively. The experimental results proved that both of the obtained complexes had scavenging effect on superoxide-anion free radical and showed catalytic activities in the polymerization of methyl methacrylate as well.

Key words: Noncyclic polyether Schiff base, Co(Ⅱ) and Ni(Ⅱ) complex, Catalytic activity
