- Scope
- This document describes the procedure for the determination of butadiene microstructure and styrene content in solution polymerized styrene-butadiene rubber (S-SBR) by Fourier transform infrared spectroscopy (FTIR) attenuated total reflectance (ATR) method. Styrene content is the mass fraction relative to the whole polymer. 1,4-trans structure, 1,4-cis structure and 1,2
