Abstract

The invention provides a synthesis method of an acrolein polymer. Azobisisobutyronitrile is adopted as a catalyst for catalysis of polymerization of acrolein so that the polymerization reaction is mild and has easy control, and therefore the problems that since a traditional method adopts an inorganic base as a catalyst and an excessively quick synthesis speed, the synthesized acrolein polymer hasno uniform size, easy agglomeration and poor insulation are solved. The synthesized acrolein polymer has a good sterilization effect, and the sterilization rate can reach 95% or above; and after theacrolein polymer is used, ammonia nitrogen and nitrite in a water body are also reduced significantly, the dissolved oxygen content is also increased significantly, and the polymer can be applied to treatment of animal excrement-contaminated water or domestic sewage.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method for synthesizing an acrolein polymer and an application of the acrolein polymer. Background technique [0002] Macromolecular acrolein polymer, because its molecular group contains a large number of water-insoluble active aldehyde groups, has a strong killing effect on viruses and bacteria, and can be used to filter water contaminated by viruses and bacteria without causing water quality problems. Secondary pollution. The acrolein polymerization method generally uses an inorganic base as a catalyst, but the synthesized acrolein polymer has uneven molecular weight, is easy to agglomerate, and has poor insulation, so it is not suitable for water purification and electronic packaging. [0003] Based on this, it is necessary to provide a new synthesis method of acrolein polymer. Contents of the invention [0004] In view of this, the present invention proposes a method...
