Two novel bithiazole-containing polyamides, DClAI and DTTPA, and their complexes were synthesized by condensation and complexation. Novel homogeneous composite films were prepared by in situ blending these complexes with polyvinyl alcohol. These polymeric complexes and composite films were characterized by FTIR. The magnetic properties of the complex and its related composite film were measured using a physical property measurement system. It was found that the properties of films are similar to those of their related polymeric complexes. (C) 2004 Wiley Periodicals, Inc.
