Rubber latex — Styrene-butadiene — Determination of bound styrene content

This document specifies a method for the determination of the bound styrene content of styrene-butadiene rubber (SBR) lattices.

The method is applicable to hot (approximately 50?°C) emulsion polymerized SBR lattices having a bound styrene content, expressed on the SBR content, of up to 55?% and to cold (approximately 5?°C) emulsion polymerized SBR lattices having a bound styrene content between 18?% and 40?%.

The method is not applicable to reinforced styrene-butadiene rubber (SBR. .Y) lattices, carboxylic-styrene-butadiene rubber (XSBR) lattices and pyridine-styrene-butadiene rubber (PSBR) lattices.
