  • Why is cationic fragment structure important in a template copolymer?
  • The cationic fragment structure in the template copolymer could help to generate large and dense floc structure and form stable drainage channels. Under external pressure, these large and compact floc structures had greater compressive resistance, which avoided deformation and blockage of drainage channels and voids.
  • Is mw-TP assigned to free radical initiated polymerization?
  • In addition, the test results of association constant (K M) and polymerization kinetics showed that the MW-TP was assigned to free radical initiated polymerization and the polymerization mechanism was I Zip-up (ZIP). It confirmed the formation of cation fragment structure again.
  • How cationic microblock structure is formed on tpamd molecular chain?
  • An evident and continuous cationic microblock structure was formed on TPAMD molecular chain through MV-TP. The microblock structure had higher positive charge density, thus having strong charge neutralization, excellent electrical patching, and higher positive charge utilization efficiency.
  • What happens when cationic monomers are added to cpamd?
  • When the anionic template sodium polyacrylate (NaPAA) is added to the reaction system of CPAMD, cationic monomer DAC can be adsorbed to NaPAA by electrostatic force, and then, cationic monomers will be continuously arranged along the molecular chain of the template, thereby forming precursors with cationic microblock structure (Guan et al. 2014).
