摘要
以ｎ－ＢｕＬｉ为催化剂，切割后的制苯抽余油［（８１±２）℃］为溶剂，对丁二烯和苯乙烯的嵌段共聚进行了５Ｌ聚合釜实验。结果表明，试样为嵌段共聚物；在相同条件下，与生产ＳＢＳ所用溶剂相比，试样的收率随着制苯抽余油的质量分数增加而减少；二者的物理机械性能基本相当。
Copolymerization of butadiene and styrene in a 5 L reactor with n-BuLi as catalyst in different solvents was studied.The results showed that 40% extracted oil from benzene production could meet the demands.All the copolymers were characterized by IR and GPC.
