A series of polymer blends of commercial poly(viny1 chloride) (suspension-polymerized powder) and an ethylene-vinyl acetate copolymer (EVA with 45 w t % VA) containing 2-10 wt % EVA were prepared by mixing at room temperature (0) and by milling at 160Β°C for 15 min (I) and then heat treated at 170Β°C
Copolymers of vinyl chloride-vinyl acetate have been prepared with different vinyl acetate contents and molecular weights and under different polymerization conditions. A rheological study of these copolymers indicates that they behave in some ways like externally plasticized PVC. For instance, as t
