Analysis of Polyvinylchloride using Gel Permeation Chromatography

Abstract: Chlorinated PVC with a maximum concentration of 73 % of chloride is used whenever the plastic material needs to have drastically increased solubility compared to normal PVC. Chlorination also improves thermal stability and mechanical stability. Examples of products made from this modified PVC are resins, foil and fibers. To ensure the highest quality, molecular weight (MW) data have to be evaluated for each batch of produced polymer. Gel Permeation Chromatography is an analytical tool used to characterize polymers which are soluble in organic solvents.
