摘要
采用IR和UV光谱法证明了IBVE/Cl_2/TiCl_4/CH_2Cl_2体系得到的聚合物链末端的结构,由此探讨了该体系链转移终止反应机理及减少链转移终止反应的途径。
Various structures of the polymer chain end prepared by IBVE/ Cl2/TiCl4/ CH2C12 were studied spectroscopically. Both lowering polymerization temperature and electron donor addition can minimize the chain transfer termination . According to UV and IR data and the fact of carboxyl and conjugate double bonds signal, the mechanism of chain transfer reaction was proposed.
