Benzocrown ether graft polymer with lithium isotopic separation effect and preparation method thereof |
| abstract |
The present invention relates to a benzocrown ether graft polymer exhibiting a lithium isotope separation effect and a method for producing the same. The main chain of the polymer is a main chain of a polymer containing a chloromethyl group, an acyl chloride group or a hydroxyl group, the side chain is a benzocroton ether, and a benzocaine ether graft polymer is formed through chemical crosslinking do. The process for preparing the polymer is as follows. That is, a polymer containing a chloromethyl group, an acyl chloride group or a hydroxyl group is added to a polymer solution prepared at a constant concentration in a solvent, and a polymer solution containing a catalyst and a carboxyl group or an acid group Or an acid binder and an amino or hydroxyl benzocaine ether are mixed and dissolved in a polymer solution containing a chloromethyl group or an acyl chloride group and allowed to react at a constant temperature and a constant reaction time and the benzocaine ether is subjected to chemical crosslinking To the polymer backbone, and a precipitant is added to precipitate to obtain a graft polymer. The graft polymer has excellent lithium isotope separation characteristics. |
