Styrene-butadiene rubber, raw. Determination of soap and organic-acid content Ingestion-build-264231 BS 3SP discusses scope1 Scope This document specifies three methods for the determination of the soap and organic acid content of raw styrene butadiene rubber (SBR). Method A is the titration method using indicator reagent. Method B is the titration method using an automatic potentiometric titrator. Method C is the back titration method using an automatic potentiometric titrator. Since the soaps and organic acids present in the rubber are not single chemical compounds, the
