Abstract
The invention relates to a norbornene, acrylics and octafluorocyclopentene ternary polymerization catalyst. The norbornene, acrylics and octafluorocyclopentene ternary polymerization catalyst is characterized in that Fe(6-[1-{(2-methyl)imino}ethyl]-2-acetylpyridine)Cl2, tris(n-butylcyclopentadienyl)yttrium, carbon tetrachloride and a first solvent are placed in an inertia dry single-opening glass bottle, the bottle opening is sealed through a latex tube, and the ternary polymerization catalyst is obtained after dissolution. Norbornene monomers, acrylics monomers and octafluorocyclopentene monomers are prepared according to the mole ratio of 1:1:1, the mixture is added to an inertia dry container, and a second solvent is added to the container so that the mixture can be dissolved. The ternary polymerization catalyst is added and reacts for 2 hours to 8 hours at the constant temperature of 30 DEG C to 90 DEG C, the product is poured into a methanol solution containing 4.5 wt% to 5.5 wt% of hydrochloric acid so that the copolymer can deposit, the sediment is washed through methyl alcohol to be neutral and then dried in vacuum, and then the norbornene, acrylics and octafluorocyclopentene terpolymer is obtained. Raw materials of the catalyst are low in price and can be easily obtained, the catalytic efficiency is high, the reaction temperature is low, and the copolymer yield is high.
