合成了4种取代茚基均配及混配型的茂金属化合物(1-C6H5CH2Ind)2MCl2(M=Ti(1),zr(2))、(1-C6H5CH2Ind)CpMCl2(M=Ti(3),zr(4)).通过IR、1H NMR、EI-Ms和元素分析对化合物进行了表征.用所合成的茂金属化合物与MAO所组成的催化体系,研究了乙烯的聚合.发现金属为Ti的催化剂没有聚合活性或活性极低.金属为zr的催化剂有一定的催化活性,不同的催化剂得到的聚合物性质有一定的差异.
The substituted indenyl metallocene complexes (1-C6H5CH2Ind)2MCl2(M=Ti(1),Zr(2))and (1-C6H5CH2Ind)CpMC12 (M=Ti (3), Zr (4)) were synthesized and characterizd by IR、1H NMR,EI-MS and elemental analysis. It is found that the compounds(2) and (4) could be used for catalytic polymerization of ethylene in the presence of MAO with products of [M]η=(31.4~39.5)×104.
