Problems solved by technology

However, due to the problems of its production process and formula, there will be a large amount of insoluble matter after it dissolves, which will affect the product quality
[0004] Existing bead polymers belong to the homopolymer of polydimethyldiallyl ammonium chloride. Due to the dispersant used and the operation problems of the production process, the product made has a large amount of insoluble matter and the viscosity is not enough. The product will seriously affect the printing and dyeing, daily chemical industry, etc.
[0005] The existing bead polymer belongs to the homopolymer of dimethyl diallyl ammonium chloride, the cationic degree cannot be adjusted, the intrinsic viscosity is low, and the application range is relatively narrow

Abstract

The invention belongs to the technical field of preparation of high-molecular compounds, and particularly relates to a bead-shaped hyperviscosity water-soluble cationic polymer and a preparation method thereof. The preparation method of the bead-shaped hyperviscosity water-soluble cationic polymer adopts the technical scheme that the preparation method comprises the following steps of according to parts by mass, adding 1 to 5 parts of dispersant into a reaction kettle, adding 200 to 500 parts of organic hydrocarbon solvent of aviation kerosene, putting into a water bath pot at room temperature, stirring, and filling a nitrogen protection reaction system under liquid level. The bead-shaped hyperviscosity water-soluble cationic polymer has the advantages that the dissolving speed is high, the viscosity is high, the cationic degree can be adjusted, and the like; the bead-shaped hyperviscosity water-soluble cationic polymer is widely applied into water treatment, papermaking, petroleum production, textile printing and dyeing, daily chemical engineering, and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of macromolecular compounds, and in particular relates to a bead-like ultra-high viscosity water-soluble cationic polymer and a preparation method thereof. Background technique [0002] The existing industrial products of polydimethyldiallylammonium chloride and its cationic copolymers are mainly aqueous solution polymers and a small amount of powder polymer products. Aqueous solution polymer is mainly a product in which monomers are polymerized to a certain molecular weight and then diluted with water to a certain concentration. Because the product contains a large amount of water, it not only increases the packaging cost, but also increases the transportation cost; the powder polymer is mainly polymerized through the solution bulk. The product is processed in a pulverizing dryer, which is difficult to produce, high in cost, and cannot be mass-produced. The product is powdery and difficult to...
