Influence of processing parameters and molecular weight on the mechanical properties of PVC

The role of a variety of processing parameters in determining the mechanical properties of solid PVC has been examined. Annealing pretreatment has been shown to increase both the yield stress and the modulus. It was found that the density of the material similarly increased as the annealing progressed, and when the density reached a limiting value, the yield stress and modulus also reached a limiting value. The molecular weight of the resin, as …
