Abstract

Two pairs of asymmetric

-ketoimine isomers containing a hydroxyl group and the corresponding tridentate titanium complex isomers

Ti1

Ti2

and

Ti3

Ti4

were synthesized

and the isomeric ligands and complexes were confirmed by FTIR

H-NMR

C-NMR

elemental analysis

and single-crystal X-ray diffraction (XRD) characterization. Under the action of the cocatalyst MAO

both pairs of titanium complex isomers exhibited high activity for ethylene polymerization and copolymerization with

-olefins. Furthermore

the ethylene (co)polymerization activities of complexes

Ti2

and

Ti4

with the side arm near the phenyl group were significantly higher than those of the corresponding isomers

Ti1

and

Ti3

with the side arm near the hydroxyphenyl group. For ethylene polymerization

the activity of complex

Ti4

with the methioaniline side arm was the highest

which was three times that of its isomer

Ti3

and more than twice that of the similar structural complex

Ti2

with the methioethylamine side arm and the control titanium complex

Ti5

without the hydroxyl group. Moreover

Ti4

showed extremely high thermal stability

which can maintain extremely high activity above 10

g·mol

-1

·h

-1

at an ethylene pressure of 1.0 MPa and a high temperature of 100 ℃

and still had high activity at 120 ℃. In the copolymerization of ethylene and

-olefins (1-hexene and 1-octene)

the copolymerization activity and insertion rate of the comonomer catalyzed by the complexes

Ti3

and

Ti4

containing methylaniline side arms were significantly higher than those catalyzed by

Ti1

and

Ti2

with methioethylamine side arms

with a copolymerization activity of over 10

g·mol

-1

·h

-1

Ti4

exhibited the highest copolymerization activity

whereas the comonomer insertion rate obtained using

Ti3

was the highest. The structure optimization of the

-ketoimine tit

anium complex isomers was calculated using density functional theory (DFT)

and the results were consistent with the trend of the ethylene (co)polymerization activity and the thermal stability of the complexes. The complex

Ti4

only required overcoming a relatively small activation energy barrier to complete chain growth

exhibiting the highest catalytic activity and strongest thermal stability.
