摘要
对ｎ－Ｃ８Ｈ１７ＯＨ－ＢＦ·ＯＥｔ２（Ｂ）预混、ＣＨ３ＣＯＯＣ４Ｈ９－Ｂ预混和稀Ｂ单加三种体系的聚合行为进行了比较。结果表明，当Ｂ组分中加入ｎ－Ｃ８Ｈ１７ＯＨ时，可有效地提高聚丁二烯的相对分子质量；而加入ＣＨ３ＣＯＯＣ４Ｈ９，可在不影响聚合物相对分子质量的前提下拓宽Ａｌ／Ｂ值。
The polymerization behaviors of three kinds of system, the premixing of n-C8H17OH-BF3·OEt2,the premixing of CH3COOC4H9-BF3·OEt2 and dilute BF3·OEt2(B), were compared.The result showed that the molecular weight of polybutadiene increased effectively by adding n-C8H17OH to B component.The addition of CH3COOC4H9 to B component did not chang the molecular weight, but widened the suitable range of Al/B ratio.
