摘　　要：以大内径碳纳米管、羟基化碳纳米管及氯化镁作载体,采用高能球磨技术制备了纳米级钛系ZieglerNatta催化剂,研究了该催化剂对反式聚异戊二烯聚合过程的影响。结果表明,反式聚异戊二烯/碳纳米管复合材料具有管状结构,碳纳米管颗粒分散良好,并且明显提高了反式聚异戊二烯的热稳定性。In this research, large inner diameters carbon nanotube(CNTL), hydroxylated carbon nanotube(CNTOH) and magnesium chloride(MgCl 2) are used as the carriers and the high-energy ball-milling technique is adopted to prepare in situ loaded titanium chloride(TiCl 4) Ziegler-Natta catalyst. The effects of carbon nanotube(CNT) on trans -polyisoprene(TPI) were investigated. The morphologies of TPI/CNT nanocomposites exhibited a tube-like shape and the CNT particle were well dispersed within the entire TPI matrix. In addition, the thermal stability of the TPI were significantly enhanced by the introduction of very small amount of CNT particle. As shown in Fig 1, CNTOH and CNTL disentangle and disperse uniformly in catalysts. In the prepared catalysts lamella MgCl 2 inserts between CNT and partially covers on the surface of the CNT, which would weak the π-π interaction between CNT.
