| 中文摘要 | a series of novel vanadium(iii) complexes bearing iminopyrrolide chelating ligands [2-(rn=ch)c4h3n]v(thf)(2)cl-2 (2a: r = cyclohexyl; 2b: r = ph; 2c: r = 2,6-ipr(2)c(6)h(3); 2d: r = p-cf3c6h4; 2e: r = c6f5) have been synthesized and characterized. single-crystal x-ray diffraction revealed that complexes 2a, 2c and 2e adopt an octahedral geometry around the vanadium center. in the presence of et2alcl as a co-catalyst, these complexes displayed high catalytic activities up to 48.6 kg pe mmol(v)(-1) h(-1) bar(-1) for ethylene polymerization, and produced high molecular weight polymers. 2a-e/et2alcl catalytic systems were tolerant to elevated temperature (70 degrees c) and yielded unimodal polyethylenes, indicating the single site behaviour of these catalysts. by pre-treating with equimolar amounts of alkylaluminums, functional alpha-olefin 10-undecen-1-ol can be efficiently incorporated into polyethylene chains. 10-undecen-1-ol incorporation can easily reach 15.8 mol% under the mild conditions. |
