| titleOfInvention | Preparation method and application of efficient cationic polymer |
| abstract | The invention discloses a preparation method of a high-efficiency cationic polymer, which specifically comprises the following steps: step 1, synthesizing a cationic polymer with a long branched chain structure: step 1.1, sequentially adding an initiator, a solvent, a precursor and a monomer into a flask, introducing nitrogen for 20-40min, and placing the flask in a water bath for reaction; step 1.2, precipitating with ethanol after the reaction is completed, and drying at 50-70 ℃ to obtain a cationic polymer with a long branched chain structure; step 2, synthesizing a high-efficiency cationic polymer: step 2.1, dispersing the obtained cationic polymer with the long-chain branched structure into a tetrahydrofuran solution, and reacting for 4-6h at the temperature of 25-35 ℃; 2.2, precipitating the obtained product with ethanol for multiple times, and then centrifugally washing to obtain a solid product, and drying the obtained solid product at the temperature of 50-70 ℃ to obtain the high-efficiency cationic polymer; the invention also discloses application of the polymer, and the polymer can improve the impact resistance, continuous catalytic performance and operation stability of immobilized biological enzyme. |
