ActiveStyrene-butadiene rubber(SBR)—Determination of the microstructure of solution-polymerized SBR—Part 2:FTIR with ATR method
苯乙烯-丁二烯橡胶(SBR) 溶液聚合SBR微观结构的测定 第2部分:红外光谱ATR 法
Application Summary AI generated
This standard specifies the use of Fourier Transform Infrared Spectroscopy (FTIR) with Attenuated Total Reflectance (ATR) to determine the microstructure of solution-polymerized styrene-butadiene rubber (S-SBR), specifically measuring the content of styrene and the three butadiene isomers (cis-1,4, trans-1,4, and vinyl-1,2). It is applied in the rubber and plastics industry for quality control, raw material verification, and product development of S-SBR used in high-performance tires, footwear, and other engineered elastomers. The method provides a rapid, non-destructive testing alternative to traditional techniques, ensuring consistent polymer composition for optimized processing and end-use performance.
