| titleOfInvention | A kind of water-soluble cationic cyclodextrin polymer and preparation method thereof |
| abstract | The invention provides a preparation method of a water-soluble cationic cyclodextrin polymer. The preparation method has simple steps, the prepared polymer has high molecular weight, still has good water solubility after being placed for a long time, and at the same time retains the cyclodextrin cavity and has a lamellar dendritic structure. The method includes: polymerizing cyclodextrin, 2,3-epoxypropyltrimethylammonium chloride and ethylene glycol under alkaline conditions to obtain a water-soluble cationic cyclodextrin polymer. In the present invention, 2,3-epoxypropyltrimethylammonium chloride is used to replace the commonly used 2,3-epoxypropyltrimethylammonium chloride, and the cyclodextrin polymer is positively charged. Through the synergy of charge attraction and inclusion, the interaction strength between the cyclodextrin polymer and the hydrophobically associative polymer can be further enhanced, so as to further improve the cyclodextrin polymer and the hydrophobically associative polymer mixed solution. Rheological properties; on the other hand, adding ethylene glycol in the reaction reduces the content of active groups, making the reaction conditions milder and the end point more controllable, and the obtained product will not further increase the degree of cross-linking, so the product can be It still maintains good water solubility after a long standing time. |
