Abstract
By using the ~(13)C-NMR data, the sequential distribution of styrene-butadiene copolymer initiated by n-BuLi-THF under "quasi-stationary" condition has been investigated. Some important informations, such as average block lengths for monomer units and mixed monomer blocks, the variation of alternating microstructure etc., have been evaluated.
