| 英文摘要 | A novel late transitional metal catalyst-(2-me-3-clph)(2)pbime2fecl2-has been synthesized having a high oligomerization activity up to 1.0 x 10(7)g oligomer/( mol fe (.) it). using this oligomenization catalyst and metallocene catalyst-rac-c2h4 (ind)(2)zrcl2-as a dual functional catalyst system, mao as the only cocatalyst, linear low density polyethylene (lldpe) has been prepared by in situ copolymerization of ethylene having a high activity [> 10(6)g pe/( mol cat (.) h)]. c-13-nmr shows that the lldpe is obtained. in addition, the presence of unreacted alpha-olefin was not detected since there is no evident resonance signal at 29.29 and 29.42, which proves that this dual functional catalyst system has a good match during in situ copolymerization. with increasing the fe/zr ratio, the densities of polymers and the melting points of polymers obtained from dsc are in a descending trend. meanwhile, the similar phenomenon is also found when the reaction temperature decreases. |
