scope:

This method provides a procedure for extracting plasticizers, mineral oils, extenders, low molecular weight waxes, prelubricants as in "preswollen" compounds, and other soluble additives typically found in polymers. It is also useful in obtaining an "oil-free", additive-free base elastomer for cognate analysis by Thermogravimetric Analysis (TGA) and Infrared Analysis (IR). Selection of the appropriate solvent is based upon the type of polymer, requirements of the Engineering Material Specification, and/or knowledge of the solvent and anticipated solubilities of the materials to be extracted (i.e., alcohols may extract more selectively than acetone).
