Abstract

A method is described for the determination of chlorine in resins from polyvinyl chloride compositions. It is based on preliminary isolation of the resin by ether extraction of the sample, followed by fusion of the resin in an electrically fired Parr bomb. The solution of the melt is acidified slightly, and the chloride is then titrated potentiometrically with standard silver nitrate solution.
