Physical and conductivity properties of poly (vinyl chloride) ionomers

Poly (vinyl chloride)(PVC) is a cheapest plastic. Importance of PVC based ionomer has been gradually being popularizing due to compatibility of PVC with a number of salts to replace polyethylene oxide based ionomer. Under present investigation few of chloride group of PVC chain have been replaced by basic thiouronium group and these thiouronium groups are further oxidized to sulfonate group. Introduction of thiouronium group in PVC is confirmed through FTIR and further its oxidation to sulfonate group is also confirmed by FTIR. Conductivity in different stoichiometric ratio of PVCTU and PVCSO₃H was studied and found that PVCTU: PVCSO₃H in 1:1 ratio has conductivity near to pure PVC (10⁻⁹ Ohm-1 cm⁻¹) and increases with proportion of PVCSO₃Na in the mixture (10⁻⁶ Ohm⁻¹ cm⁻¹) for pure PVC, PVCTU has less conductivity not much significant.
