| titleOfInvention | Preparation method of cation organic silicon modified polyacrylamide |
| abstract | The invention discloses a preparation method for cation organic silicon modified polyacrylamide, which comprises the following steps of: firstly, uniformly mixing organic silicon monomer, cation monomer, acrylamide and water; introducing nitrogen for dispersing oxygen, and then adding an initiator; and performing free radical polymerization under ultrasonic assistance, thereby obtaining the cation organic silicon modified polyacrylamide. Due to the high-efficient dispersive action of ultrasonic wave, the organic silicon monomer is excellently dispersed in water solution and is copolymerized with hydrophilic monomer, without adding emulsifying agent or surface activity monomer. According to the preparation method provided by the invention, the usage of the emulsifying agent or surface activity monomer is avoided, so that the HAPAM after-treatment is fully eliminated, the preparation process is simplified and the production efficiency is increased. |
