采用UV光谱法首次证明了IBVE/Cl_2/TiCl_4/Toluene聚合体系中同时存在着两种引发活性中心及络合竞争,研究了Cl_2/TiCl_4和H_2O/TiCl_4络合平衡,求出了20℃时2TiCl_4←Cl_2和TiCl_4←H_2O络合平衡不稳定常数。
The UV-visible spectroscopy was the first time to prove that there are two kinds of active centers and complexation competition in the IBVE / Cl_2 / TiCl_4 / Toluene polymerization system. The complexation of Cl_2 / TiCl_4 and H_2O / TiCl_4 was studied. ← Cl_2 and TiCl_4 ← H_2O complex equilibrium unstable constant.
