| 中文摘要 | the copolymerizations of ethylene with polar hydroxyl monomers such as 10-undecen-1-ol, 5-hexen-1-ol and 3-buten-1-ol were investigated by the vanadium(iii) catalysts bearing bidentate [n,o] ligands (1, [phn=c(ch3)chc(ph)o]vcl2(thf)(2): 2, [phn=chc6h4o]vcl2(thf)(2); 3, [phn=chc(ph)cho]vcl2(thf)(2)). the polar monomers were pretreated by alkylaluminum before the polymerization. high catalytic activities and efficient comonomer incorporations can be easily obtained by changing monomer masking reagents and polymerization conditions in the presence of diethylaluminium chloride as a cocatalyst. the longer the spacer group, the higher the incorporation of the monomer. under the mild conditions, the incorporation level of 10-undecen-1-ol reached 13.9 mol% in the resultant copolymers was obtained. the reactivity ratios of copolymerization (r(1) = 41.4, r(2) = 0.02, r(1)r(2) = 0.83) were evaluated by fineman-ross method. according to c-13 nmr spectra, polar units were located both on the main chain and at the chain end. |
