| titleOfInvention | Preparation method of high isotactic poly 2-vinylpyridine |
| abstract | The invention relates to a preparation method of high isotactic poly 2-vinylpyridine, which is characterized by comprising the following steps: dissolving a catalyst in toluene or chlorobenzene as a first solution in an inert atmosphere; dissolving organic boron salt in toluene or chlorobenzene as a second solution; dropwise adding the second solution into the first solution at room temperature under stirring, and continuously stirring for 3-7 min to form a third solution; adding a 2-vinylpyridine monomer into the third solution under an inert atmosphere to form a polymerization reaction system with the monomer solubility of 0.5-2.0 mol/L, stirring at room temperature at 300-500 rpm for 0.5-5 h to perform polymerization reaction, and then dropwise adding 0.4-0.6 ml of methanol to terminate the polymerization reaction; then adding 50-100 ml of petroleum ether to settle out the poly 2-vinylpyridine; and carrying out suction filtration and separation on the precipitate, and carrying out vacuum pumping at 40-70 ℃ to obtain the high isotactic 2-vinylpyridine polymer. |
