<div class="htmlview paragraph">Ultimate tensile properties are examples of a physical property which is relatable to the molecular weight of a polymer. Dilute solution viscosities of vinyl chloride homopolymers have classically been used to obtain an average molecular weight - tensile relationship. However, dilute solution viscosity measurements of todays' dispersion resins may not be a true indication of the PVC tensile strength.</div> <div class="htmlview paragraph">Molecular weight distribution, from high speed GPC, have shown a direct correlation with PVC homopolymer ultimate tensile strength.</div> <div class="htmlview paragraph">In addition, this technique will provide for rapid separation and quantitation of plasticizers and other additives in compounded PVC resins.</div>
