摘要
研究了［ｔ－ＢｕＯＡｃ］、［ＴｉＣｌ４］／［ｔ－ＢｕＯＡｃ］（摩尔比）对ｔ－ＢｕＯＡｃ／ＴｉＣｌ４／ＩＢ／ＣＨ２Ｃｌ２体系聚合反应的影响．通过紫外光谱分析，证明了本体系中存在着ＴｉＣｌ４←Ｈ２Ｏ、ｔ－ＢｕＯＡｃ→ＴｉＣｌ４两种络合引发活性中心和它们之间的络合竞争，提出了抑制ＴｉＣｌ４与Ｈ２Ｏ络合引发的条件，解释了［ｔ－ＢｕＯＡｃ］、［ＴｉＣｌ４］／［ｔ－ＢｕＯＡｃ］对聚合反应的影响规律．
The effect of [t-BuOAc], [TiCl4]/[t-BuOAc] on carbocationic polymerization of t-BuOAc/TiCl4/CH2Cl2 system were investigated. There coexist at least two initiating centers by UV-Vis spectrographic analysis. The condition of complexation controlling of TiCl4 and H2O was also inverstigated and the law of [t-BuOAc], [TiCl4]/[t-BuOAc] effecting on polymerization is explained as well.
