| titleOfInvention | A kind of nonionic solid polyacrylamide and preparation method thereof |
| abstract | The invention discloses a nonionic solid polyacrylamide and a preparation method thereof, belonging to the field of high molecular polymers and preparation thereof. Including: dissolving the functional monomer and the first complexing agent in deionized water, stirring evenly, and preparing the first polymerization solution; The first polymer solution is pre-initiated by redox, and then the photo-initiated functional monomer pre-polymer solution and acrylamide monomer are used to polymerize to form a colloid; finally, a non-ionic solid is prepared. Polyacrylamide. In the invention, the redox method is used to pre-initiate functional monomers, and then acrylamide is mixed in to initiate light-initiated ribbon polymerization under different light intensities, so as to increase the content of functional monomers in the acrylamide copolymer, and to control the highest temperature rise during the polymerization process. Therefore, the non-ionic solid polyacrylamide has ultra-low hydrolysis degree and ultra-low residual monomer content. |
