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 Under present investigation few of chloride group of PVC chain have been replaced by basic thiouronium group and these thiouronium groups are further oxidized to sulfonate group.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.
