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.
