What are cationic polyacrylamide copolymers?

Cationic polyacrylamide copolymers are manufactured in four different general product forms. These are aqueous solutions, dry polymer powders and beads, water-in-oil inverse emulsions and microemulsion, and aqueous brine dispersions .

How is cationic polyacrylamide produced?

Cationic polyacrylamides can be produced via copolymerization with a cationically charged vinyl monomer or by postreaction of the homopolymer of acrylamide with cationizing species. Of the two, the copolymerization route is the most widely used across all product forms.

What are the types of industrial polyacrylamides?

The types of flocculants, in other words industrial polyacrylamides, are cationic, anionic or nonionic polyacrylamides. Kemira’s polyacrylamides of wide range of charge and molecular weight are sold in dry powder or emulsion format and have excellent performance.

What is a high molecular weight nonionic polyacrylamide?

High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants , , . 34.2.5. Polyacrylamide product forms The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders.

Can cationic polyacrylamides be used as strength resins?

The use of modified cationic polyacrylamides as strength resins in papermaking is well known . The preparation of a useful product consists of the reaction of a cationic polyacrylamide with the dialdehyde glyoxal and was first reported in 1971 . Strength resins generally come in a solution form.

What are nonionic polyacrylamide products?

Again, nonionic polyacrylamide products are available as aqueous solutions, liquids (inverse emulsions), and dry powders. Nonionic polyacrylamides are available from very low to very high molecular weights and are used in industrial wastewater treatment, mineral process, papermaking, and other industries.
