  • What are the different types of cationic polyacrylamide synthesis technologies?
  • There are four main kinds of cationic polyacrylamide synthesis technologies: in aqueous solution, in dispersion, by inverse emulsion, or through photoinitiated polymerization . These methods had experienced numerous developments and modifications such as free radical copolymerization or grafting processes .
  • How is cationic polyacrylamide obtained?
  • In the photoinitated polymerization method (Fig. 4), the cationic polyacrylamide is obtained by photoactivation of monomer solution. This synthesis technique is characterized by many advantages: operation simplicity, easy control, low cost, and obtained product has high purity [11, 12].
  • Are cationic binders prepared by direct surfactant-free emulsion polymerization method?
  • There is lots of work in the preparation of cationic latex , , , , , and surfactant-free emulsion. However, a small number of publications deal with cationic binders prepared by direct surfactant-free emulsion polymerization method.
  • Is a cationic acrylate Binder a good emulsifier?
  • Ji and her co-workers reported the synthesis of a cationic acrylate binder with cetyltrimethylammonium bromide and XL-50 as emulsifiers by emulsion polymerization. The cationic binder was better than the conventional anion binder in terms of calcium ion stability, wet rubbing fastness, color fastness to washing and hand feel.
