摘要
研究了单体转化率为（７０±２）％时，叔十二碳硫醇（ＴＤＭ）的用量、加入方式对共聚物ＭＬ、相对分子质量及其分布和性能的影响。结果表明，改变ＴＤＭ用量和加入方式，可以有效地控制聚合物的相对分子质量及其分布，抑制支化和凝胶的产生。
The effects of amouant and addition form of tert-dodecyl mercaptan (TDM) on Mooney viscosity, molecular weight distribution and properties of copolymers were studied in order to obtain the E-SBR with high conversion. It was shown that the molecular weigh and its distribution, structure and properties of E-SBR could be efficiently controlled by changing the amount and regulating way of TDM.
