Rubber. Analysis by pyrolytic gas-chromatographic methods - Determination of styrene/butadiene/isoprene ratio Ingestion-build-48348 BS EN 4640-002 talks about1 Scope This part of ISO 7270 specifies a pyrolytic gas chromatographic method for the determination of the styrene butadiene isoprene ratio in copolymers, or blends of homopolymers and or copolymers, in raw rubbers or in unvulcanized or vulcanized compounds. It is applicable to copolymers terpolymers consisting of styrene, butadiene and isoprene, and blends of these polymers. NOTE 1 The use of this part of ISO 7270 pre supposes sufficient working
