Describes a method to determine the bound acrylonitrile content of emulsion-polymerized NBR latices with a bound acrylonitrile content, expressed as a percentage of the polymer content of between 18% and 45%. Also applies to carboxylic-nitrile-butadiene (XNBR) latices and nitrile-isoprene (NIR) latices.

This International Standard specifies a method for the determination of the bound acrylonitrile content of emulsion-polymerized NBR latices having a bound acrylonitrile content, expressed as a percentage of the polymer content, of between 18 % and 45 %. The method is also applicable to, for example, carboxylic-nitrile-butadiene (XNBR) latices and nitrile-isoprene (NIR) latices.

NOTE 1 The determination includes any water-insoluble nitrogen-containing additives present in the latex.
