Rubber latices. Methods of test. Determination of bound styrene content of non-reinforced styrene butadiene rubber latices | Status: Superseded, Withdrawn

1 Scope and field of application This International Standard specifies a method for the determination of the bound styrene content of styrene-butadiene rubber (SBR) latices. The method is applicable to hot (approximately 50 °C) emulsion polymerized SBR latices having a bound styrene content, expressed on the SBR content, of up to 55 % and to cold (approximately 5 °C) emulsion polymerized SBR latices having a bound styrene content between 18 and 40 %. The method is not applicable to reinforced styrene-butadiene rubber (SBR..Y) latices, carboxylated-styrene-butadiene rubber (XSBR) latices and pyridine-styrene-butadiene rubber (PSBR) latices.
