【Abstract】 The influence of water on anionic polymerization system of butadiene is studied by lots of experiments and theoretical analysis. The deactivation formula of active species with LiOH is shown and the concept of initiation content is proposed at the first time.Herefrom the experimental phenomena of initiation and propagation processes and the influence of water content on the structure of the products are explained, thus provide a scientific basis for the design work of polymer synthesis.更多还原
