英文名称：Rubber — Analysis by pyrolytic gas-chromatographic methods — Part 2: Determination of styrene/butadiene/isoprene ratio
发布日期：2005-03
标准范围
This part of ISO 7270 specifies the principles and procedures for determining, by pyrolysis and subsequent gas chromatography, the styrene (STY)/butadiene (BD)/isoprene (IP) ratio in copolymers, or blends of homopolymers and/or copolymers, in raw rubbers or vulcanized or unvulcanized compounds.It is applicable to copolymers/terpolymers consisting of styrene, butadiene and isoprene, and blends of these polymers.NOTE 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.
