Preparation, Structural Characterization, Thermal and Electrical Studies of Cobalt(II) Chloride and Zinc(II) Chloride Compounds of Poly(Acrylamide)
The reaction of poly(acrylamide) with cobalt(II) chloride and zinc(II) chloride produced compounds of stoichiometry [Co(C3H5NO)10Cl26H2O]n and [Zn(C3H5NO)14Cl2H2O]n. In these compounds the metal ions are in tetrahedral environments. Thermal decomposition studies show that these compounds first lose water followed by the organic ligand and halogen to give the metal oxides. Poly(acrylamide) was found to have a glass transition temperature of 168-degrees-C. The room temperature electrical conductivities for poly(acrylamide) and its cobalt and zinc polymers lie in the range 9.97 X 10(-8) to 7.71 X 10(-7) and show ohmic conductivity.
