Six new poly-Schiff bases have been synthesized by solution polycondensation of six different diamines with 4,4'-aryl bis-(oxy)-bis acetophenone. The synthesized polymers were characterized by viscosity measurement, elemental analyses, i.r., X-ray diffraction, and differential scanning calorimetry.
Ten new polyesterazomethines have been synthesized by solution polycondensation of five different diamines with 4,4'-[terephthaloyloxy]bis-3-ethoxybenzaldehyde and 4,4'-[isophthaloyloxy]bis-3-ethoxybenzaldehyde using dimethylacetamide in the presence of anhydrous LiCL. Fibrous polymers were precipit
## SYNOPSIS Two new conjugated poly-Schiff bases (PPpP and PPmP) were synthesized by polycondensation of p-phenylene diamine or m-phenylene diamine with 2,6-pyridine dicarboxaldehyde. PPpP and PPmP can form charge transfer complexes with iodine. Maximum conductivity of PPpP-iodine complex at room
