Rubber, raw styrene-butadiene, emulsion-polymerized — Determination of bound styrene content — Refractive index method
Preview
Summary
This document specifies a method for determining the bound styrene content of emulsion-polymerized
styrene-butadiene rubbers (SBR) by correlation with the measured refractive index of an extracted
sample according to a table of refractive indices versus percentage mass fractions styrene.
The method is also applicable to extracted oil-extended emulsion-polymerized SBR as long as it produces
a film suitable for refractive index measurements. It is not applicable to solution-polymerized SBR.
