An obvious catalytic heterogeneity of Cat 2 (Complex 2/DMAO) towards ethylene polymerization was observed, which was illustrated by decreased activity, multimodal molecular weight distribution and partially improved particle morphology comparing with Cat 1. Moreover, Cat 3 exhibits “living” characteristics in the process under certain conditions (25 °C, less than 20 min). Otherwise, the moderate to high ethylene polymerization activity of ca. $ 10^{5} $–$ 10^{6} $ g PE/(mol Ti·h) and high molecular weight (Mw = $ 10^{5} $–$ 10^{6} $) of polyethylene can be obtained by changing the skeleton structure of these complexes.

An obvious catalytic heterogeneity of Cat 2 (Complex 2/DMAO) towards ethylene polymerization was observed, which was illustrated by decreased activity, multimodal molecular weight distribution and partially improved particle morphology comparing with Cat 1. Moreover, Cat 3 exhibits “living” characteristics in the process under certain conditions (25 °C, less than 20 min). Otherwise, the moderate to high ethylene polymerization activity of ca. $ 10^{5} $–$ 10^{6} $ g PE/(mol Ti·h) and high molecular weight (Mw = $ 10^{5} $–$ 10^{6} $) of polyethylene can be obtained by changing the skeleton structure of these complexes.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ethylene polymerization</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Catalytic heterogeneity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">“Living” polymerization</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Phenoxy-imine ligand</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">4-Vinylphenyl group</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fan, Hong</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jie, Su-yun</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Bo-geng</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Chinese Journal of Polymer Science</subfield><subfield code="d">Chinese Chemical Society and Institute of Chemistry, CAS, 2009</subfield><subfield code="g">32(2014), 7 vom: 22.

abstract	Abstract This contribution reports ethylene polymerization behavior of titanium complexes incorporating bis(phenoxyimine) ligands. Six phenoxy-imine Ti(IV) complexes {6-$ R^{1} $-2-[CH=N(2,6-difluoro-3,5-$ diR^{2} $-4-$ R^{3} $Ph)]$ C_{6} %$ H_{3} $O}2$ TiCl_{2} $ (1: $ R_{1} $ = H, $ R_{2} $ = H, $ R_{3} $ = H; 2: $ R^{1} $ = H, $ R^{2} $ = H, $ R^{3} $ = 4-vinylphenyl; 3: $ R^{1} $ = $ CH_{3} $, $ R^{2} $ = H, $ R^{3} $ = H; 4: $ R^{1} $ = $ CH_{3} $, $ R^{2} $ = H, $ R^{3} $ = 4-vinylphenyl; 5: $ R^{1} $ = $ CH_{3} $, $ R^{2} $ = F, $ R^{3} $ = H; 6: $ R^{1} $ = $ CH_{3} $, $ R^{2} $ = F, $ R^{3} $ = 4-vinylphenyl) have been synthesized and evaluated for ethylene polymerization using dried MAO (simplified as DMAO) as cocatalyst. An obvious catalytic heterogeneity of Cat 2 (Complex 2/DMAO) towards ethylene polymerization was observed, which was illustrated by decreased activity, multimodal molecular weight distribution and partially improved particle morphology comparing with Cat 1. Moreover, Cat 3 exhibits “living” characteristics in the process under certain conditions (25 °C, less than 20 min). Otherwise, the moderate to high ethylene polymerization activity of ca. $ 10^{5} $–$ 10^{6} $ g PE/(mol Ti·h) and high molecular weight (Mw = $ 10^{5} $–$ 10^{6} $) of polyethylene can be obtained by changing the skeleton structure of these complexes.
