Popis

BS ISO 2453:2020


This standard BS ISO 2453:2020 Rubber, raw styrene-butadiene, emulsion-polymerized. Determination of bound styrene content. Refractive index method is classified in these ICS categories:
  • 83.040.10 Latex and raw rubber
  • 83.060 Rubber

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.
