DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 78 The title polymn. catalyst has a structure I (R1 = tert-Bu, pyridyl, Ph, methylphenyl, ethylphenyl, dimethylphenyl, etc.; R2, R3, R4, R5 and R6 = H, Me, Et, iso-Pr or OMe). The polymn. catalyst is manufd. by carrying out a condensation reaction of b-diketone compds. 326-90-9 and 919998-36-0 are also in the experiment. contg. trifluoromethyl group with aniline or its derivates in methanol to obtain Schiff base, carrying out a reaction of the Schiff base with Bu lithium under anhyd. and anoxic condition to obtain anionic ligand, and carrying out coordination reaction of the anionic ligand and vanadium trichloride under anhyd. and anoxic condition to obtain the final product. The catalyst can catalyze polymn. of ethylene, and copolymn. of ethylene and a-olefin or norbornene combined with di-Et aluminum chloride or modified methylaluminoxane. .
