| description | The invention belongs to the technical field of multipolymer. The invention provides a multipolymer dispersant and a preparation method thereof, and the multipolymer dispersant is obtained by mixing N-vinyl pyrrolidone, maleic anhydride, N, N-dimethylacrylamide, 2-acrylamide-2-methylpropanesulfonic acid, an initiator and water and then reacting. The invention also provides an application of the multipolymer dispersant. In the multi-polymer dispersing agent disclosed by the invention, a sulfonic acid group of 2-acrylamide-2-methylpropanesulfonic acid and a rigid ring of N-vinyl pyrrolidone jointly improve the high temperature resistance and salt resistance of the polymer dispersing agent; a rigid cyclic group on the N-vinyl pyrrolidone can protect an amide group at a high temperature and prevent the amide group from being hydrolyzed, so that the stability of the polymer is improved, and the API filter loss is reduced.
本发明属于多元聚合物技术领域。本发明提供了一种多元共聚物分散剂及其制备方法，将N-乙烯基吡咯烷酮、马来酸酐、N,N-二甲基丙烯酰胺、2-丙烯酰胺-2-甲基丙磺酸、引发剂和水混合后进行反应 |
