Example Embodiment
[0019] Example 1
[0020] Take 0.01 mole of 2-acetyl-6-(2-methylbenzimidyl) ethyl pyridine iron chloride, 0.01 mole of tris(butylcyclopentadiene) yttrium, 0.01 mole of carbon tetrachloride and 20 ml of cyclohexane The ketone is put into a single-mouth glass bottle that has been evacuated and baked with nitrogen for many times, and the mouth of the bottle is sealed with a latex tube to obtain an iron-gadolinium complex catalyst.
[0021] Add 0.01 mole of bicyclo[2,2,1]hept-2-ene, 0.01 mole of tert-butyl methacrylate and 0.01 mole of octafluorocyclopentene monomer into a single-port glass that has been evacuated and baked with nitrogen for many times In the bottle, add 5ml cyclohexanone to dissolve. Take the iron-gadolinium complex catalyst according to the amount of 2-acetyl-6-(2-methylbenzimidyl)ethylpyridinium chloride as 1% of the total weight of the three monomers, and inject the above mixture with a syringe Put the single-mouth glass bottle into a constant temperature water t...

[0024] Example 2
[0025] Take 0.01 mole of 2-acetyl-6-(2-methylbenzimidyl) ethyl pyridine iron chloride, 0.08 mole of tris(butylcyclopentadiene) yttrium, 0.05 mole of carbon tetrachloride and 20 ml of toluene. Put it into a single-mouth glass bottle that has been evacuated and baked with nitrogen for many times, and the mouth of the bottle is sealed with a latex tube to obtain the iron-gadolinium complex catalyst.
[0026] Add 0.01 moles of 1-methylbicyclo[2,2,1]hept-2-ene, 0.01 moles of ethyl acrylate and 0.01 moles of octafluorocyclopentene monomer into a single port that has been vacuumed and baked with nitrogen for many times In a glass bottle, add 5ml of toluene to dissolve. Take the iron-gadolinium complex catalyst according to the amount of 2-acetyl-6-(2-methylbenzimidyl)ethylpyridinium chloride as 4% of the total weight of the three monomers, and inject the above mixture into the syringe , Put the single-mouth glass bottle in a constant temperature water tank and react a...

[0027] Example 3
[0028] Take 0.01 mole of 2-acetyl-6-(2-methylbenzimidyl) ethyl pyridine iron chloride, 0.05 mole of tris(butylcyclopentadiene) yttrium, 0.04 mole of carbon tetrachloride and 20 ml of toluene. Put it into a single-mouth glass bottle that has been evacuated and baked with nitrogen for many times, and the mouth of the bottle is sealed with a latex tube to obtain the iron-gadolinium complex catalyst.
[0029] Add 0.01 moles of bicyclo[2,2,1]hept-2-ene, 0.01 moles of methyl methacrylate and 0.01 moles of octafluorocyclopentene into a single-mouth glass bottle that has been evacuated and baked with nitrogen for many times. Add 5ml toluene to dissolve. Take the iron-gadolinium complex catalyst according to the amount of 2-acetyl-6-(2-methylbenzimidyl)ethylpyridinium chloride as 3% of the total weight of the three monomers, and inject the above mixture with a syringe Put the single-mouth glass bottle in a constant temperature water tank and react at 90°C for 8 hours. ...
