Preparation and Characterization of Polystyrene (Pst) and Poly Vinyl Chloride (Pvc) Alloys.

Alloys of polystyrene (PST) and poly (vinyl Chloride) (PVC) were prepared by solvent casting techniques. These results were interpreted in terms of the interactions between the components of these blends. Physio chemical characteristics of the products were studied. It was found that at certain relative concentration, some of these properties were enhanced, while some degraded relatively to the constituent homo polymers. By means of FT infra red studies, it was established that functional groups were the major players in interactions. Other modes include dipole-dipole, van der waals and mere physical entanglements.
