| titleOfInvention | Polyvinyl pyridine preparing method |
| abstract | The invention relates to a high-yield controllable polyvinyl pyridine synthetic method at room temperature, which includes the steps: firstly, configuration of a reaction system, wherein the reaction system comprises polyvinyl pyridine monomer, initiator, a catalyzing system and solvent, the mole ratio of the polyvinyl pyridine monomer, the initiator and the catalyzing system is 100-1000:1:1, and the mole ratio of the monomer to the solvent is 1:0.5-3; and secondly, preparation of polyvinyl pyridine by 'activity'/ controllable free radical polymerization reaction at 20-30 DEG C. The polyvinyl pyridine polymer is successfully synthetized at the room temperature for the first time by the method, the yield can reach more than 90%, and the precision structure of copolymerized compound is successfully regulated. Further, the polymerization system can be operated without ligand, less zero-valent copper powder is used as catalyst, post-treatment is convenient, and industrial production is facilitated. |
