中文摘要 | a series of novel vanadium(iii) complexes hearing heteroatoill-containing group-substituted salicylaldiminato ligands [rn=ch(aro)]vcl2(thf)(2) (ar = c6h4, r = c3h2ns, 2a; c7h4ns, 2c; c7h5n2, 2d; ar = c(6)h(2)tbu(2) (2,4), r = c3h2ns, 2b) have been synthesized and characterized. structure of complex 2c was further confirmed by x-ray crystallographic analysis. the complexes were investigated as the catalysts for ethylene polymerization in the presence of et2alcl. complexes 2a-d exhibited high catalytic activities (up to 22.8 kg polyethylene/mmolv h bar), and affording polymer with unimodal molecular weight distributions at 25-70 degrees c in the first 5-min polymerization, whereas produced bimodal molecular weight distribution polymers at 70 degrees c when polymerization time prolonged to 30 min. the catalyst structure plays an important role in controlling the molecular weight and molecular weight distribution of the resultant polymers produced in 30 min polymerization. in addition, ethylene/hexene copolymerizations with catalysts 2a-d were also explored in the presence of et2alcl, which leads to the high molecular weight and unimodal distributions copolymers with high comonomer incorporation. |
