摘要

正

The quantitative description of the sequence structure of emulsion-processed SBR and solution-processed SBR （by lithium catalyst）was carried out based on their spectral data Of

C-NMR.The calculating formulae which could be used to obtain diad concentration from the peak intensifies of carbon spectra

average block length

average number of block

and the microstructure composition of the molecular chain were derived. The quantitative result showed that on the molecular chain styrene unit had the tendency to attach to trans-1

4 butadiene unit. The calculated result of the microstructure was in good agreement with that obtained through IR measurement.
