▎ 摘  要

NOVELTY - Preparing fluorine-containing isobutylene and isoprene polymer involves adding 1200-1500 pts. wt. ionic liquid and 100 pts. wt. fluorinated graphene in a mortar, and grinding at room temperature for 6-10 hours to obtain an ionic liquid modified fluorinated graphene viscoelastic fluid. The air of polymerization vessel is replaced with nitrogen three times under normal pressure, and then the polymerization temperature is reduced to -50 degrees C to -100 degrees C, 100 pts. wt. methyl chloride is added as a solvent, 1-5 pts. wt. ionic liquid modified fluorinated graphene viscoelastic fluid is also added, stirred for 10-30 minutes, then 20-35 pts. wt. isobutylene and 2-3.5 pts. wt. isoprene are added, and stirred for 10-30 minutes. 0.2-0.6 pts. wt. Initiator 0.2-0.6 pts. wt. terminator are added, and stirred for 30 minutes to 3 hours. The terminated solution is flash-vaporized, filtered, and dried to obtain a finished product. USE - Method for preparing fluorine-containing isobutylene and isoprene polymer.
