| titleOfInvention | Novel macromolecular self-supported salicylaldimine metal titanium complex, and synthesis method and use method thereof |
| abstract | The invention discloses a novel macromolecular self-supported salicylaldiminium metal titanium complex, a synthetic method and a using method. The invention takes allyl-substituted salicylaldiminato metal titanium complex and ethylene as raw materials, and prepares a novel macromolecular self-supported salicylaldiminato metal titanium complex D by copolymerization 1 ～D 6 The resulting titanium complex D 1 ～D 6 The catalyst can efficiently catalyze the homopolymerization of the N-vinyl pyrrolidone, has extremely low monomer NVP and catalyst residue rate, and can meet the quality requirement of high-quality pharmaceutical grade PVP. The resulting titanium complex D 1 ～D 6 Can also be dispersed in the solution of N-vinyl pyrrolidone to catalyze the solution polymerization of N-vinyl pyrrolidone. Titanium complexes D 1 ～D 6 Can be used as a catalyst for recycling. Compared with the existing method for catalyzing the polymerization of N-vinyl pyrrolidone, the macromolecule self-supported salicylaldehyde imine metal titanium complex catalyst has high polymerization efficiency, no residue is generated after the catalyst is recovered, and the requirements of high-quality medical grade PVP on the contents of monomers, catalysts and other impurities can be better met. |
