GB/T 28728-2012
ActiveDetermination of the microstructure of solution-polymerized SBR
溶液聚合苯乙烯-丁二烯橡胶（SSBR）微观结构的测定
Application Summary AI generated
This standard specifies the method for determining the microstructure of solution-polymerized styrene-butadiene rubber (SSBR), including the content of bound styrene, vinyl, cis-1,4, and trans-1,4 units. It is applied in the rubber industry for quality control and product development of SSBR, particularly in the production of high-performance tires and other elastomeric products where precise polymer composition affects processing and end-use properties. The standard is used by manufacturers and testing laboratories to ensure consistency in raw material specifications and to correlate microstructure with rubber performance characteristics.
