Description / Abstract:
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 knowledge of the principles and techniques of gas
chromatography for the analyst to perform the operations described
and interpret the results correctly.
NOTE 2 The styrene/butadiene/isoprene ratio determined by this
test method is affected by the presence of resin and by a high
level of sulfur.
