合成了 4种取代茚基均配及混配型的茂金属化合物 ( 1 -C6 H5 CH2 Ind) 2 MCl2 ( M=Ti( 1 ) ,Zr( 2 ) )、( 1 -C6 H5 CH2 Ind) Cp MCl2 ( M=Ti( 3) ,Zr( 4) ) .通过 IR、1 H 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 .
Four kinds of substituted indenyl and mixed metallocene compounds (M = Ti (1), Zr (2)) and (1 -C6 H5 CH2 Ind) Cp The compounds were characterized by IR, 1 H NMR, EI-MS and elemental analysis. The catalytic system composed of the synthesized metallocene compound and MAO was studied The polymerization of ethylene showed that the catalysts with Ti as metal had no polymerization activity or very low activity.The catalysts with Zr as metal had certain catalytic activity and the properties of polymers obtained by different catalysts were different.
