| titleOfInvention | A kind of preparation method of graft-modified polyacrylamide |
| abstract | The present application relates to the technical field of polymer preparation, and specifically discloses a method for preparing graft-modified polyacrylamide, comprising the following steps: dissolving modified soluble starch and acrylamide in water, adding an initiator after mixing, and then introducing Nitrogen is used to remove oxygen, then heated to 40°C to 50°C to initiate the reaction, and the graft-modified polyacrylamide is obtained after the reaction is completed. The graft-modified polyacrylamide prepared in the application has good flocculation effect and high stability during storage and transportation, which can effectively reduce the viscosity and flocculation effect caused by polymer degradation during storage and transportation.
