The supported metallocene catalyst wasprepared by immobilized on SiO2 with pre-contacted compounds of rac-Me2Si(Ind)2ZrCl2 and methylaluminoxane (MAO), and its activity for propylene isospecific polymerization reaches 106gPP/mol.

• 将rac-Me_2Si(Ind)_2ZrCl_2与甲基铝氧烷(MAO)预络合后负载于SiO_2上得到了负载型茂金属催化剂，并用于丙烯等规聚合，活性可达到10~6gPP/mol.
