摘　　要：在2L丙烯本体聚合釜上,进行了新型配体负载的茂金属催化剂催化丙烯聚合研究,对聚合活性、颗粒形态等进行了考察,并通过红外、核磁共振(NMR)、X射线衍射(XRD)等表征手段对聚合产品进行了结构剖析。结果表明:不同负载茂金属催化剂的活性相差较大,CAT-1的活性和堆积密度最高,分别为1830 g/gcat、0.42 g/cm^(3),同时茂金属聚丙烯的核磁结构与Z-N催化剂生产的聚丙烯相差较大。A novel ligand supported metallocene catalyst was used to catalyze propylene polymerization in a 2 L propylene bulk polymerization kettle.The polymerization activity and particle morphology were investigated and the structure of the products was analyzed by infrared,nuclear magnetic resonance(NMR),X-ray diffraction(XRD).The results show that the activity of metallocene catalysts under different loads varies greatly,and the activity and packing density of CAT-1 are the highest(1830 g/gcat,0.42 g/cm^(3)),and the nuclear magnetic structure of metallocene polypropylene differs greatly from that of polypropylene produced by Z-N catalyst.
