A dynamic method of density titration for the characterization of powders of suspension poly(vinyl chloride) (PVC) and of their fractions obtained by sieve analysis is described. The method is based on the distribution of PVC particles in variously concentrated aqueous solutions of sodium nitrate according to their specific weight. Separated phases are determinated volumetrically. The method makes possible characterization of various types of PVC powders and of their anomalies.
