氧对 n-BuLi-THF 体系丁苯共聚的影响

Effect of oxygen content on styrene butadiene solution copolymerization initiated with n BuLi THF

考察了氧分子与锂活性种快速失活的定量关系，二代杂质对活性种以及聚合物的微观结构的影响．从聚合动力学和聚合物相对分子质量两方面来测定活性种数，从而证明了氧对ｎ－ＢｕＬｉ－ＴＨＦ体系丁苯共聚合有较大影响．

? How many lithium reactive species we killed by one oxygen molecule has been studied, and the effect of the second generation impurity on anionic reactive species and microstructure is also introduced. The amount of reactive species is investigated by the methods of polymerization kinetics and molecular weight. The effect of oxygen content on styrene butadiene solution copolymerization initiated with n BuLi THF has been obtained.
