研究了Ｎｉ（ｎａｐｈ）２－Ａｌ（ｉ—Ｂｕ）３—ＢＦ３·ＯＥｔ２＋ｎ—Ｃ８Ｈ１７ＯＨ（简称Ｎｉ—Ａｌ—Ｂ十ＲＯＨ）和Ｎｉ（ｎａｐｈ）２－Ａｌ（ｉ—Ｂｕ）３－ＢＦ３·ＯＥ１２十ＣＨ３ＣＯＯＣ４Ｈ９（简称Ｎｉ－Ａｌ—Ｂ＋ＢＡ）两体系在加氢汽油中引发丁二烯聚合的分子量控制方法，并与Ｎｉ－Ａｌ—Ｂ体系进行了比较。结果表明：在催化剂用量相同时，Ｎｉ—Ａｌ—Ｂ＋ＲＯＨ和Ｎｉ－Ａｌ—Ｂ＋ＢＡ两体系所得聚合物的分子量均比Ｎｉ—Ａｌ—Ｂ体系的高；Ｎｉ／Ｂｄ、Ａｌ／Ｎｉ比的变化对聚合物的分子量及其分布影响不显著，Ａｌ／Ｂ比才是影响聚合物分子量的关键因素；聚合温度升高，分子量降低，而分子量分布变化不大。
The effects of Ni (naph) 2-Al (i-Bu) 3-BF3 · OEt2 + n-C8H17OH and Ni (naph) 2-Al (i-Bu) 3-BF3 · OE12 CH3COOC4H9 (referred to as Ni-Al-B + BA) two systems in the hydrogenation of gasoline initiated polymerization of butadiene molecular weight control method, and with the Ni-Al-B system were compared. The results show that the molecular weights of the polymers obtained from Ni-Al-B + ROH and Ni-Al-B + BA systems are higher than that of Ni-Al-B system at the same catalyst dosage. The molecular weight and its distribution had no significant effect. The Al / B ratio was the key factor affecting the molecular weight of the polymer. The polymerization temperature was increased while the molecular weight was decreased, while the molecular weight distribution did not change much.
