Synthesis and elemental analysis of metallocene analogic complexes (NpCpTiCl 2) containing the azole ligand (Np) are described,in which Np is Pr=Pyrolyl (C 4H 4N)(1); Id=Indolyl (C 8H 6N)(2); Ai=7 Azaindolyl (C 7H 5N ...Synthesis and elemental analysis of metallocene analogic complexes (NpCpTiCl 2) containing the azole ligand (Np) are described,in which Np is Pr=Pyrolyl (C 4H 4N)(1); Id=Indolyl (C 8H 6N)(2); Ai=7 Azaindolyl (C 7H 5N 2)(3); Iz=Indazolyl (C 7H 5N 2)(4); Bi=Benzimidazolyl (C 7H 5N 2)(5),respectively.It is proved by the experiments that NpCpTiCl 2 is active for ethylene polymerization at 30℃ and 0.1?mPa with MAO activation,and the results show that the activity of 1 and 2 which contain one nitrogen in the azole ring is higher than 4 and 5 which contain two nitrogens,while 3 is inactive.For the NpCpTiCl 2/MAO system,the activity is “up and down” type with increase in the Al/Ti molar ratio,and up to the highest when the Al/Ti molar ratio is about 500.The polyethylene obtained is characteristic of narrow distribution with molecular weight M w around 35×10 4 and molecular weight ratio M w/ M n less than 3.展开更多
