Resumen
Describes a method for the determination of the soap and organic-acid content of raw styrene-butadiene rubber (SBR). The method depends on the extraction of the organic acids and soaps from the rubber by means of a solvent. Recommends to determine both contents on separate portions of the same solvent extract; gives only an approximative value. Replaces the first edition.
