PVC polymer matrix

One primary requirement for plasticization is that a plasticizer must be thoroughly mixed and incorporated into the PVC polymer matrix. This is accomplished by heating with mixing, until the plasticizer is incorporated into the resin. The plasticized material is then molded or shaped into the useful product and cooled. Different plasticizers will exhibit different characteristics in both the ease with which they form the plasticized material and in the resulting physical properties of the flexible product. 

The oxidative polymerization of the diffused pyrrole in the binary solvent system of acetonitrile and methanol gives high conductivity of the polypyrrole as well as the good penetration of the oxidant into the PVC polymer matrix. The mole ratio of acetonitrile to methanol in the binary solvent system with 1.0 mole of FeCls showed optimum in the range of 0.80 to 0.85.
