| titleOfInvention | A kind of cation matrix polymer extracted available for heparin and preparation method thereof |
| abstract | The present invention is the application on a kind of cation matrix polymer and its preparation method and in heparin extraction.Utilize the existing distinctive three dimensional skeletal structure of melamine sponge, chitosan coat is coated on skeleton, reacted again by diethylene glycol (DEG) diglycidyl ether and chitosan coat, it is crosslinked it and carries substantial amounts of epoxide group on surface, then epoxide group and diethylamine reaction generation tertiary amine group are utilized, again quaterisation is carried out with dithyl sulfate, make skeleton surface because of the cation with suspension strong hydrophilicity, and pass through the electrostatic interaction with sulfuric acid anion on heparin macromolecular, realize efficient absorption, key effect is played during heparin is extracted from intestinal mucosa.Advantage using this material is：High adsorption capacity, operation simplifies, and material can be recycled for multiple times, and reduces cost, improves production efficiency. |
