| 摘 要： | 研究了生产顺丁橡胶（ＢＲ）用Ｎｉ（ｎａｐｈ）＿２－Ａｌ（ｉ－Ｂｕ）＿３－ＢＦ＿３·ＯＥｔ＿２（Ｎｉ－Ａｌ－Ｂ）催化体系的聚合活性，考察了“Ａｌ－Ｎｉ陈化，稀Ｂ单加”催化体系的稳定性。结果表明，该催化体系的组分化、陈化方式对聚合活性有极大影响；“Ａｌ－Ｎｉ陈化，稀Ｂ单加”催化体系有较好的耐时性，形成的活性中心有较高的耐温性。

| Abstract: | The catalytic activity of the nickel catalyst system, Ni(naph)2-Al(i-Bu)3-BF3OEt2(NiAl-B), in the production of cis-1,4-polybutadiene(BR) was studied,and its stability in each aging process of catalyst was investigated. The results showed that the aging process of Al and Ni, and feeding alone dilute B had higher catalytic activities,the formed active seeds had higher heat resistance. |
